However, the design of the products, especially mechanical products in the design means, is unable, failed to keep pace with the needs of the times. At present, computer-aided product design drawings, design, manufacturing, production planning has been a relatively extensive and in-depth study and achieved initial results, and product development programmes of the early computer-aided design is far from meeting a need. To this end, the author read a lot of literature on the basis of a summary of the design and scholars at home and abroad to design the method used, and discussed the various methods of organic link between product design and mechanical Computer trend of development. Under the current domestic and foreign scholars to design machinery design methods used by the main features of the programme can be summed up modern design for the following four major types. 1, systematic design method Systematic design of the main features are: design as from a number of design elements of a system, every design element of independence, there are various elements of the organic links and a level of all the design elements Combined, you can design systems to achieve the task. Systematic design idea in the 1970s by the German scholar Professor Pahl and Beitz, a system based on the theory, developed a design of the general pattern, and advocate of the design work should be rational. German Engineers Association in this on the basis of design, develop standards VDI2221 "technology systems and product development design methods. The development of the product design process of mechanical model, basically follow the German standards VDI2221 the design. In addition, many of our product design and scholars in the programme design and also learn from other developed countries cited the systematic design, which is representative: (1) The user needs as the product concept of functional characteristics, structural design and part design, process planning, operations control, and so on the basis of the product development process of the macro, the use of Quality Function layout methods, systems and information needs of users will be reasonable and effective And converted to the various stages of product development objectives and operations 设计巴巴工作室www.88doc88.com control technology means a point of order. (2) products as organisms on the level of life, and life systems through the use of the product design process can demand level of success and realize the concept of functional requirements of the specific levels and product design level. At the same time using the system icons to life the abstract expression of the functional requirements of products, product features a system structure. (3) the mechanical design system in the application of science into two basic questions: First, to design products as a system to process, to determine the best of its components (modules) and their mutual relations and the other is the product design Process as a system, according to the design objectives, correct and reasonable to determine the design of all aspects of the work and the various design stage. As each designer to study issues and to consider the perspective of the different emphases, to design a programme of specific research methods also differ. Here are some representative of the systematic design methods. 1.1 design elements of With five design elements (functions, effects, effects of vector, shape and surface elements parameters) described "product solution" that a product design elements of the five identified, all the characteristics of products and value characteristics already identified. Chinese scholars have also adopted similar design methods described product of the original understanding. 1.2 graphical modeling law Development of the design analysis and guidance systems "KALEIT, with a clear level of the graphic description of the product structure and functions related to the abstract information, and the system structure and function of the graphical modeling, and the function of the connection between. Will be assisted design divided into two methods and information exchange, the use of Nijssen information analysis methods can be used graphic symbols, with a variety of semantic model structure, the integration can be described conditions can be divided into binding type, can relations between any combination of features , Will design solutions and information technology integration, the design process to achieve a different level of abstraction of information between the graphical modeling. The literature [11] semantic network design as a design tool in the development of the semantic network design ASK, using nodes and a network of lines describing the design, components of the node that the unit design tasks, functions, components 设计巴巴工作室www.88doc88.com or processing Equipment, etc.), and lines used to adjust the definition node between different semantic relations, which in the design process for all the activities and results of pre-built model, the early design requirements to the definition of a specific structure can be described by the relationship between The definition of the expression, and a computer-aided design process from abstract to concrete leap. 1.3 "idea" - "design" law Will be divided into product design "concept" and "design" in two stages. "Idea" phase of the mission is to seek, select and design portfolio to meet the requirements of the original understanding of tasks. "Design" stage of work is the concrete realization of the original understanding of the conceptual stage. The programme will be "ideas" for the specific description: According to a suitable functional structure, designed to meet the requirements of the mandate of the original understanding. Functional structure of the sub-function by "structural elements" to achieve, and "structural elements" of the physical connection between the definition of "functional carrier", "functional carrier" and "structural elements" and formation of the interaction between the functional diagram ( Mechanical movement diagram). Programme of "design" is based on functional diagram, the first qualitative description of all the "functional carrier" and "structural elements", then all the quantitative description of "structural elements" and connecting pieces ( "functional vector") the shape and location have The structure of. Roper, H. use of graph theory theory, the help from his definition of "total design unit (GE)", "structure elements (KE)", "functional structure elements (FKE)", "connecting structure elements (VKE)", "Structural parts (KT)", "structural elements parts (KET)" concept, and describes elements of size, location and transmission parameters of the relationship between the number of thumbs, the design intuitive design experts design "stage. From the design methodology of the point of view, the design task will be clear after the design work is divided into three steps: 1) access to functions and functional structure (referred to as "functional"), 2) find effects (referred to as the "effect"); ) To find structure (referred to as "the configuration of the Rules"). And use the following four strategies described machinery idea stage of the process: Strategy 1: were considered "functional" and "effect" and "configuration rules." Therefore, we can work in various steps to create variations in the respective programmes, resulting in the original understanding of the broad spectrum. Strategy 2: "effect" and 设计巴巴工作室www.88doc88.com "configuration rules" (including the designer to create the rules) association, to consider a separate function (usually associated with the design task). At this point, to identify the typical configuration rules and their effects need to have a wealth of experience, the programme spectrum far less than a strategy of the programme spectrum. Strategy 3: "functional" and "effect", "configuration rules" are closely related. Applicable to the function, and the configuration of the rules of no choice, with special requirements of the areas, such as ultra-small machinery, large machinery, high-value function parts, and those with special requirements of the functional components, and so on. Strategy 4: In view of the structural design requirements of the solution. The strategy starting from the existing parts, through different parts of the order and connection, was expected to function. 1.4 Matrix Design In the programme design process used in "requirement - to" logic tree ( "or" tree) described requirements, the relationship between the function, to satisfy the requirements of functional design solution set, a different design. According to "request - to" logic tree establishment of a "request - to" association matrix, meet the requirements necessary to describe the complex relationship between function, expressed functional requirements and the relationship between the one-to-one. otaetal will matrix as a mechanical system design basis, the mechanical system design space as a functional decomposition of space, only that each sub-space design of a module, in the abstract phase of the high-level, with each module design movement conversion matrix And a vector for the operation of restraint that in the abstract phase of the low-rise, each module design parameters were expressed as a matrix and the equation of motion. 1.5 bond graph Law Will form a system components into the function to generate energy, energy consumption, changing energy forms, such as various types of energy transmission and use of bond graph of the function of the components that will be based on the functions of the model and bonding with plans to achieve functional The automatic generation of structural and functional structure and bonding between the automatic conversion plans to seek bond graph generated by a number of design methods. 2, modular design structure From the perspective of planning products: the definition of its mandate to design features of the product structure is based on the use of existing products (such 设计巴巴工作室www.88doc88.com as GM parts components, etc.) described the design task, that is, when the mandate of decomposition on each task to consider whether there is the corresponding Solutions products, so that in the planning stages of product design tasks to eliminate the contradictions that might exist in the early forecast production capacity, costs and the development of the process of designing the plan adjustable, which can improve the design efficiency and design of reliability, At the same time also reduce the cost of new products. Feldmann will describe the function of the design task is divided into four levels of product structure, (1) products ? (2) functional components ? (3) main function components ? (4) functional components. And the use of application-oriented features of the directory structure, a more specific functional components of the qualitative and quantitative description. At the same time developed for early in the product development and design tools used by early STRAT. Machinery specialized for most of that function can be used existing product solutions and new solutions with only a small number of special features, therefore, for the use of mechanical design features of the product structure, machinery specialized for the evaluation of the design, manufacture risk is very beneficial. Functional Analysis of the products promoted on the basis of the product is broken down into a function of one or more of the basic modular structure, through the selection and combination of these modular structure formed into various products. These basic structure can be parts, components, or even a system. The ideal modular structure should be standardized interface (connectivity and with the Department of), and is serialized, universal, integrated, hierarchical, flexible, economic, with interchangeable, compatibility and relevance of the . China's combination of software component technology and CAD technology, design and composition of deformation design combined, according to grade modular theory, machine processing center will be divided into Youdadaoxiao product level, component level, component-level and component level, and use CAD technology and expertise to their portfolio into different species, different specifications of the functional module, the module from the combination of these functions into different processing center overall programme. To select a design for the directory structure of the variation machinery tools, the design of the proposed elements for a complete, structured format, a solution set design directory. And Set Design listed in the directory comment on each of the 设计巴巴工作室www.88doc88.com additional information, very beneficial to design engineers choice of the elements. According to the connectivity features of mechanical parts and components, will be summarized into four types: 1) The components of direct targeting, and self-adjustment of parts, 2) a common structure of the assembly, 3) have nested structure and inlay Shell-like components of the connection, 4) a modular architecture and modular components of the connection. And a quasi-symbols that the typical components and rules of the connection between the components, to achieve this connection between the components of the algorithm and the concept of visualization. In the mechanical system design, "features a" module on the functions of decomposition, and provides the best functional decomposition "tablets" of the extent of the functional and institutional forms of one-to-one. "Structure to establish" as a function of the module is the choice of targets in order to achieve mapping algorithm. 3, based on knowledge of product design features Knowledge-based product design features of the main features are: to use the computer to identify the language describing the characteristics of the product design experts in the field of knowledge and experience to establish the appropriate knowledge base and reasoning machine, and then use the storage areas have been established by the knowledge and reasoning Mechanisms to achieve computer-aided design products. The mechanical system design is based on products with the characteristics, and design experts in the field of knowledge and experience to push volume and decision-making, the completion of several comprehensive. To achieve this stage of the computer-aided design, we must study the automatic acquisition of knowledge, expression, integration, coordination, management and use. To this end, the scholars at home and abroad designed for mechanical systems design knowledge of automated processing done a lot of research work, the method used can be summarized in the following few. 3.1 coding method According to "campaign conversion" feature (the function million) institutions will be classified, described and use the code function yuan and institutional categories, which established a "body system design expert system" Knowledge Base. On this basis, will be the dual logic and fuzzy comprehensive evaluation of combining theory, the establishment of the "expert systems" reasoning mechanism, and for the four-position for the design of the machine. 设计巴巴工作室www.88doc88.com Use of biological evolution theory, through natural selection and sexual reproduction to the principle of evolution of organisms to the body design, use of network theory methods to express the structure for topology, and then through the coding technology, the structure and institutions Performance of individual chromosomes into the binary string, and in accordance with design requirements of fitness, the use of biological evolution theory of reproduction control mechanism, through the selection, crossover, such as a sudden variation means to eliminate low value of the individual are not suited to the fast evolution Be the best adaptation of the individual, that is, most with the design requirements of the agency programme. 3.2 knowledge of the law mixed The complex mechanical systems design, mixed use of the knowledge expression describes the design of various types of knowledge is particularly suited to this point has been the design of many scholars of the consensus. In the development of complex product design intelligent decision support system DMDSS, will be the rules, framework, processes and neural networks, and other knowledge that organic combination of methods to adapt to different types of knowledge in the design of the description. Knowledge will be a single expression of a variety of methods (rules, framework and process), according to object-oriented programming principles, the framework of the groove with that object's properties, with rules that target the dynamic characteristics, with the knowledge that the treatment process, group Into a hybrid form of knowledge, and successfully developed the "object-oriented NC gantry milling machine gearbox design intelligent system GBCDIS" and "transmission structure design expert system GBSDES". 3.3 use of the knowledge-based development tool Coupling in the CAD system, the use of the knowledge-based development tools NEXPERT-OBJECT, through the use of object-oriented approach, to create an object-oriented database design method for coupling the designer to design and structural design Provided extensive and reliable method of the design spectrum. NEXPERT describe the use of linear guide the design of the need to design based on knowledge of the content, which seek to knowledge-based solutions, and developed a linear guide design expert system. 3.4 Design Law Directory Construction of the "modules", "functional element solution" and "institutions" three progressive design directory, and this directory of three progressive design 设计巴巴工作室www.88doc88.com principles of the programme as a mechanical transmission system intelligent design and development of the knowledge base of design Aids. 3.5 Based on the example of the way In the development of expert systems design knowledge base, using the basic predicate described design requirements, design conditions and the selected programme, described by frame "Project" and various "concept entity," through case-based reasoning of the technologies used to produce candidate With the horsepower to product design requirements. 4, Intelligent Design Intelligent Design is the main characteristics: According to the theories of design, through the use of 3D graphics software, intelligent design software and virtual reality technology, and multimedia, hypermedia tools for product development design, the concept of products, description of the product frame. 设计巴巴工作室www.88doc88.com 导言 迅速发展的科学和技术～产品功能的要求日益增多和复杂性增加了预期寿命缩短～更换速度更快。然而～产品的设计～尤其是机械产品的设计手段～是力不从心～没有跟上时代的需要。目前～计算机辅助产品设计图纸～设计～制造～生产计划已相当广泛和深入的研究～并取得初步成果和产品开发 方案 气瓶 现场处置方案 .pdf气瓶 现场处置方案 .doc见习基地管理方案.doc关于群访事件的化解方案建筑工地扬尘治理专项方案下载 的早期电脑辅助设计是远远不能满足需要。为此～作者阅读了大量的文献的基础上～总结了设计和学者在国内和国外的设计所采用的方法～并讨论了各种方法之间的有机联系产品设计和机械计算机的发展趋势。 根据目前国内和国外学者设计机械设计所使用的方法的主要特点～该方案可以概括为现代设计为以下四个主要类型。 1 、系统设计方法 系统设计的主要特点是:设计了一些设计元素的一种制度～每一个设计元素的独立性～有各种因素的有机联系和一定程度的所有设计元素结合～可以实现设计系统这项任务。系统的设计思想在20世纪70年代由德国学者教授帕尔和Beitz ～一个系统的理论基础上～制定了设计的一般模式～倡导设计工作应是合理的。德国工程师协 会在此基础上设计～开发标准VDI2221 “技术系统和产品开发设计方法。 产品设计过程的力学模型的发展基本上是按照德国标准VDI2221的设计。此外～我们的许多产品设计和学者在方案设计～并借鉴其他发达国家列举了系统设计～这是代表: , 1 ,用户需求作为产品概念的功能特征～结构设计和零件设计～工艺 规划 污水管网监理规划下载职业规划大学生职业规划个人职业规划职业规划论文 ～作业控制等的基础上～产品开发过程的宏观调控～利用质量功能布置方法～系统和信息需求的用户将是合理和有效～并转化为各阶段的产品开发目标和行动的控制技术是指一个程序问题。 , 2 ,产品的生物体水平的生活～生活系统～通过使用该产品的设计过程中可以要求的成功和实现的概念～功能要求的具体水平和产品设计水平。同时使用该系统的图标生命的抽象表达的功能要求的产品～产品功能～系统结构。 , 3 ,机械设计系统中的应用科学分为两个基本问题:第一～设计的产品作为一个系统来处理～以确定最佳的组成部分,单元,及其相互关系和其他的产品设计过程作为一个系统～按照设计目标～正确和合理地确定设计的所有方面的工作和各设计阶段。 由于每个设计者研究问题～并考虑的角度不同的侧重点～设计方案的具体研究方法也各不相同。以下是一些代表性的系统设计方法。 1.1设计要素 设计巴巴工作室www.88doc88.com 与五个设计元素,功能～效果～影响的载体～形状和表面元素参数,描述“产品解决方案” ～一个产品设计的五个要素的确认～所有产品的特点和价值特征已经确定。中国学者也采用了类似的设计方法描述产品的原始理解。 1.2图形建模法 开发设计 分析 定性数据统计分析pdf销售业绩分析模板建筑结构震害分析销售进度分析表京东商城竞争战略分析 和导航系统“ KALEIT ～并有明确的图形描述了产品结构和功能相关的摘要信息～该系统结构和功能的图形化建模～以及功能之间的联系。 将协助设计分为两个方法和信息交流～利用Nijssen信息分析方法可用于图形符号～与不同的语义模型结构～整合可以说是条件可分为结合型～可以任何关系的功能组合～将设计的解决方案和信息技术的融合～设计过程～实现不同的抽象层次之间的信息图形化建模。 文献[ 11 ]语义网络的设计～作为设计工具的发展～语义网络的设计要问～用节点和网络线路描述的设计～元件的节点设计任务的单位～职能～组成部分或加工设备～等, ～以及用于调整线的定义节点之间的语义关系～它在设计过程中的所有活动和结果预先建立模型～早期的设计要求的定义～一个具体的结构可以被描述的之间的关系的定义～表达～以及计算机辅助设计过程由抽象到具体的飞跃。 1.3 “思想” - “设计”的规定 将分为产品设计“概念”和“设计”两个阶段。 “理念”阶段的任务是寻求～选择和设计的产品来满足需求的原始理解的任务。 “设计”阶段的工作是具体实现的原始理解的概念阶段。 该方案将“思想”的具体描述:根据一个合适的功能结构～以满足任务要求的原始理解。功能结构分功能的“结构性因素” ～以实现和“结构因素”的身体之间的联系“的定义～功能性载体” ～ “功能载体”和“结构因素” ～并形成之间的互动功能图,机械运动示意图, 。方案的“设计”是基于功能图～第一次定性描述所有的“功能载体”和“结构性因素” ～那么所有的定量描述的“结构性因素”和连接件, “功能载体” ,的形状和位置有结构。罗佩尔阁下利用图论理论～从他的帮助定义的“总设计单位, GE ,的” ～ “结构元素,柯, ” ～ “功能结构元素, FKE , ” ～ “连接结构元素, VKE , ” ～ “结构零件, KT公司, ” ～ “结构因素部分,酮, ”的概念～并描述内容大小～位置和传输参数之间的关系～一些大拇指～设计直观的设计专家设计“阶段。 从设计方法学的角度来看～设计任务后～将明确的设计工作分为三个步骤: 1 ,获取功能和功能结构,称为“功能性” , ～ 2 ,找到影响,称为作为“效应” , ; ,如果要寻找结构,简称为“配置的规则” , 。并使用了以下四个战略描述机械想法阶段的进程:策略1 :被认为是“功能性”和“效果”和“配置的规设计巴巴工作室www.88doc88.com 则。 ”因此～我们可以在各个步骤～以创建不同的各自的方案～从而在原来的理解～广谱。战略2 : “效应”和“配置规则” ,包括设计者创建的规则,协会～考虑一个单独的功能,通常与设计任务, 。在这一点上～确定典型配置规则和其影响需要有丰富的经验～该方案谱远远少于战略方案谱。策略3 : “功能”和“效果” ～ “配置规则”是密切相关的。适用于功能和配置的规则别无选择～有特殊要求的领域～如超小型机械～大型机械～高价值的功能部件～而这些有特殊要求的功能部件～所以对。策略4 :鉴于结构设计要求的解决方案。该战略从现有的零件～通过不同地区的秩序和方面～预计将功能。 1.4矩阵设计 在方案设计过程中使用“的要求-对”逻辑树, “或”树,描述的要求～功能之间的关系～以满足要求的功能设计解集～不同的设计。根据“要求- ”逻辑树建立“要求- ”协会矩阵～满足必要的描述之间的复杂关系的功能～表达和功能要求之间的关系～一对一。 otaetal将矩阵作为机械系统设计的基础上～机械系统设计空间作为一个功能分解的空间～只有每个子空间的设计模块～在抽象阶段的高级别～每个模块设计运动转换矩阵和载体的运作克制～在抽象阶段的低层～每个模块的设计参数～表示为一个矩阵和运动方程。 1.5键合图法 将形成一个系统组件的功能来产生能源～能源消耗～改变能源形式～如各种形式的能源输送和使用的键合图的功能元件～将根据职能与模型和粘接计划～实现功能的自动生成结构和功能结构和键之间的自动转换计划寻求键合图产生的一些设计方法。 2 ～模块化设计结构 从规划的角度看产品:定义其任务是设计特点是产品结构的基础上利用现有的产品,如汽车零部件等, ～描述了设计任务～就是当任务分解对每项任务～以考虑是否有相应的解决方案产品～因此～在规划阶段的产品设计任务～以消除可能存在矛盾的早期预测的生产能力～成本和开发设计的过程中的计划调节～这可以提高设计效率和设计的可靠性～同时也降低成本的新产品。 Feldmann将描述的功能设计任务分为四个层次的产品结构～ , 1 ,产品?
