【摘要】：随着经济的快速发展，客户对机械产品的需求日益个性化和多样化，这就迫使企业必须在低成本和短交货期的前提下，不断增强自身的技术创新能力，进而赢得市场竞争力。模块化设计在这种环境下应运而生，已经逐渐成为最符合中国制造业现状和特点的先进制造技术之一。它通过科学的模块化体系，快速地将各功能模块组合成满足客户需求的个性化产品。并且由于模块的系列化设计、批量化生产和系统化管理，大大降低了产品的生产成本。因而，企业对于模块化设计理论的运用和实施有着非常迫切的需求，但是目前我国的机械产品模块化设计理论还不够完善，技术还不够成熟，特别是在模块组合环节中起到关键作用的模块接口设计还没有形成完备、系统的理论方法。基于此，本文从轮式装载机模块接口的大量实例中总结出一套基于模块化的接口设计方法，在模块化设计中与模块的变型和组合相匹配，提高模块的重利用度，促进产品的快速设计，缩短产品设计周期，，降低企业生产成本。本文以轮式装载机为研究对象，阐述了轮式装载机模块化的研究背景和发展趋势。简要说明了轮式装载机的研发特点和设计要求，指出了对其模块化的原则，展示了模块化结果，并对模块的关联情况进行了简单分析，以作为接口研究的基础。对接口的理论基础进行了总结和完善，并设计了轮式装载机模块接口的编码方法。概括了模块接口的特性，通过对接口结构和尺寸的分析，简化了接口设计。制定了确定模块接口基型的流程，应用层次分析法完成了基型主要参数的选择，进而实现了接口的系列化。而且提出了模块接口再设计，建立了接口的设计评价机制，制定了面向模块化库的接口设计文档，总结了模块接口设计的一般方法和步骤。最后以某企业5T系列轮式装载机工作装置和属具的接口设计为例，验证了本文方法的可操作性。通过对应用企业的相关调查，结果显示这种设计方法加快了轮式装载机的配置过程，提高了模块化设计的效率和质量，降低了设计者的工作强度，加快了企业响应客户需求的速度，提高了企业的市场竞争力。
[Abstract]:With the rapid development of economy, customers' demand for mechanical products is becoming more and more individualized and diversified, which forces enterprises to enhance their technological innovation ability under the premise of low cost and short delivery time, and then to win market competitiveness. Modular design emerges as the times require in this environment and has gradually become one of the most advanced manufacturing technologies in accordance with the current situation and characteristics of China's manufacturing industry. Through the scientific modular system, the functional modules are quickly combined into personalized products to meet the needs of customers. Because of the serial design, batch production and systematic management of the module, the production cost is greatly reduced. Therefore, enterprises have a very urgent need for the application and implementation of modular design theory. However, at present, the modular design theory of mechanical products in our country is not perfect enough, and the technology is not mature enough. Especially, the module interface design, which plays a key role in the module combination, has not yet formed a complete, systematic theory and method. Based on this, this paper summarizes a set of interface design methods based on modularization from a large number of examples of the module interface of wheel loader, which matches with the variant and combination of the module in the modular design, and improves the reutilization of the module. Promote rapid product design, shorten product design cycle and reduce production cost. In this paper, the research background and development trend of wheel loader modularization are described. This paper briefly describes the research and development characteristics and design requirements of wheel loader, points out the principle of modularization, shows the result of modularization, and makes a simple analysis of the correlation of the modules, which is the basis of the research on the interface. The theoretical basis of the interface is summarized and improved, and the coding method of the wheel loader module interface is designed. The characteristics of the module interface are summarized and the interface design is simplified by analyzing the structure and size of the interface. The process of determining the basic type of the module interface is worked out, and the selection of the main parameters of the basic type is completed by using the analytic hierarchy process (AHP), and the serialization of the interface is realized. Furthermore, the re-design of the module interface is proposed, the evaluation mechanism of the interface design is established, the interface design document oriented to the modular library is established, and the general methods and steps of the module interface design are summarized. Finally, the design of the interface between the working device and the equipment of the 5T series wheel loader in an enterprise is taken as an example to verify the maneuverability of this method. Through the investigation of application enterprises, the results show that this design method accelerates the configuration process of wheel loader, improves the efficiency and quality of modular design, and reduces the working intensity of designers. Accelerate the speed of enterprise response to customer demand, improve the market competitiveness of enterprises.
