【摘要】：客户在低成本、高质量和个性化方面的要求已经成为当前中国制造业共同面临的严峻挑战。模块化设计制造是迎接上述挑战的重要途径,也是最符合中国制造业现状和特点的先进制造技术。通过合理的产品模块化体系,可以快速地组合成满足客户需求的个性化产品,同时又由于通用模块的批量生产和批量管理降低了生产和管理成本。但是目前,我国企业还缺乏一个完整的、通用的和可操作的产品模块化技术方法。因此,企业的快速发展决定于模块化设计的成熟实施以及基于模块化产品平台的配置设计技术的发展。本论文将围绕产品在快速优质设计、低成本制造的需求,重点研究产品配置设计技术,并以装载机为例建立一个面向轮式装载机配置设计的平台,支持产品的快速设计,提高零部件重用率、降低产品的全生命周期成本。本文阐述了论文的研究背景,对论文的主要研究领域—大批量定制及其配置设计技术进行了概念性定义与介绍,讨论了产品平台及产品族的概念、内容和产品族配置系统。对基于产品平台的配置设计进行了总结,研究了功能相似产品的产品平台搭建问题。基于自底向上法,利用改善的产品BOM表,提出了一种建立产品平台的新方法,并将此方法应用到某企业某类装载机产品上。对于基于实例推理与配置规则相结合的配置方法以及配置规则的提取进行了研究。在基于实例推理时,利用改进TOPSIS法准确检索最相似的产品实例,并解决因有多个相似实例而无法提取的问题,对于产品设计具有一定的理论和工程价值。最后,将CAE与配置设计相结合,设计出不可再分模块的结构,检验了组合结构的工作性能,扩展了配置设计的流程。本文在产品平台的搭建、配置顺序的确定、基于实例推理的配置设计、配置设计与CAE的结合以扩展配置流程等方面均有一定的理论创新。通过相关研究,我们得到了装载机产品平台及其配置设计的方法与过程,结果显示装载机适合大批量定制设计,对于提高企业的智能化水平具有重要意义。
[Abstract]:The requirements of customers in low cost, high quality and individuation have become a serious challenge facing the Chinese manufacturing industry. Modular design and manufacturing is an important way to meet these challenges. It is also the most advanced manufacturing technology in line with the current situation and characteristics of China's manufacturing industry. Through a reasonable modularization system of products, it can be quickly combined into personalized products that meet the needs of customers. At the same time, the batch production and batch management of general modules reduce the cost of production and management. However, at present, Chinese enterprises still lack a complete, general and operable method of modularization of products. The rapid development of enterprises depends on the mature implementation of modular design and the development of configuration design technology based on modular product platform. This paper will focus on the requirements of rapid and high quality product design and low cost manufacturing, focus on product configuration design technology, and take the loader as an example to establish a platform for the configuration design of wheel loader to support the rapid design of products. Improve the reuse rate of parts and reduce the whole life cycle cost of products. This paper describes the research background of the thesis, introduces the main research field of the paper, mass customization and configuration design technology, and discusses the concept of product platform and product family. Content and product family configuration system. The configuration design based on product platform is summarized, and the problem of product platform building with similar functions is studied. Based on the bottom-up method, the improved product BOM table is used. A new method of building product platform is proposed. This method is applied to a certain kind of loader products in an enterprise. The configuration method combined with case based reasoning and configuration rules are studied, as well as the extraction of configuration rules. The improved TOPSIS method is used to accurately retrieve the most similar product examples, and to solve the problem that can not be extracted because of many similar examples, which has certain theoretical and engineering value for product design. Finally, by combining CAE with configuration design, the structure of non-separable module is designed, the working performance of the combined structure is tested, and the flow of configuration design is extended. In this paper, there are some theoretical innovations in the construction of product platform, the determination of configuration sequence, the configuration design based on case-based reasoning, the combination of configuration design and CAE to expand the configuration process. Through relevant research, we get the method and process of product platform and configuration design of loader. The result shows that loader is suitable for mass customization design, and it is of great significance to improve the intelligence level of enterprises.
