【摘要】 随着产品需求的多样化、复杂化和个性化,以缩短产品开发周期为目的的快速设计方法和技术日益受到人们的重视。而结合了模块化设计与参数化设计各自优点的参数模块化设计则是实现产品快速设计的有效途径。本文以桥式起重机小车架为研究对象,研究了用于小车架产品快速设计的参数模块化设计理论与方法。论文主要研究内容如下:(1)分析研究了现有的模块化设计方法,在对其进行比较的基础上,提出了三种产品模块设计方法----面向新产品的模块化设计方法、已有产品的变形设计以及已有产品族的模块化改造。(2)对以上三种方法的设计过程进行了总结,详细介绍了小车架的模块化设计过程。(3)将模块化设计与参数化设计以及特征造型技术相结合,提出了参数模块化设计的概念,并对创建“桥式起重机小车架的参数模块化设计平台”的开发目标、开发工具及开发方法进行了说明。(4)在所开发的设计平台支持下,进行了桥式起重机小车架的具体设计,通过实例说明了该设计平台的使用方法及应用效果。本文提出的参数模块化设计概念将模块化设计中模块划分、组合的优点与参数化设计中参数灵活变化的优点有机结合,使得模块的尺寸可根据用户的需求灵活变化。所开发的“桥式起重机小车架的参数模块化设计平台”可以根据用户输入的需求快速生成小车架产品的设计方案,具有很强的适应性和灵活性,为企业快速响应用户需求、有效减轻设计工作量提供了有效的工具。更多还原

【Abstract】 With the diversification, complication and individuation of the requirements for products, the methods and techniques for fast design of the products, aiming to reduce the product develop period, have been paid more and more attentions. By combining the advantages of modular design and parameterized design, Parameterized Modular Design has become the effective method for realizing the fast design of products. With the small frame in bridge crane as an object, this paper researched the theory and methods of Parameterized Modular Design used in the fast design of small frame. The main points of the paper are described as follows.(1) The existing modular design methods were analyzed and comparied and three modular design methods for products development were presented, i.e., new product modular design, existed product modularized redesign and modularized reform for existed product families.(2)The design processes of these three methods were summarized and the modular design process of the small frame was introduced in detail.(3)The concept of Parameterized Modular Design was presented based on the combination of the advantages of the modular design with the advantages of parameterized design and feature technique. The goals, tools and methods were introduced for the development of parameterized modular design platform for the small frame in the bridge crane.(4) The design of the small frame in the bridge crane was carried out under the support of the developed system. The using process was introduced and the effectiveness of the platform was provedThe concept of parameterized modular design presented in this paper combined the advantages of module-dividing and module-combining in modular design with the advantages of flexibility to dimension changing in parameterized design, which leads to the dimensional flexibility of the modules according to the users’requirements. The platform developed for the design of the small frame in the bridge crane can quickly generate the products design scheme according to the users input information, which would provide a helpful tool to response the users’requirements and to reduce work load of product design. The adaptability and the flexibility of the system have be proved in the practice.更多还原
