面向生命周期的铸件结构方案设计书方法研究.docVIP

摘 要 传统的铸件结构设计主要采用串行的设计方法，首先由零件结构设计人员设计出零件的基本结构，在交由铸造工艺设计人员进行铸造工艺设计和结构调整。由于零件结构设计人员对铸造工艺过程缺乏足够的认识，而铸造工艺人员又对零件结构设计的整体思想缺乏了解，彼此之间难以沟通和交流，导致铸件的设计和生产脱节。一方面浪费了大量的时间和资源，另一方面使铸件的性能难以得到保证，使铸件的设计与制造陷入尴尬的境地。 本课题围绕铸件全生命周期过程，分析了传统铸件结构设计中的不足，说明了面向生命周期的铸件结构设计的重要性，综合利用各种理论知识，包括全生命周期理论、绿色制造、并行设计、面向制造的设计等，探索一种既能满足铸件结构要求，又能适应铸造过程中工艺技术要求的可行性的优化设计方法，从而达到提高铸件设计的可行性与一次性成功率的目的。 关键词：铸件结构设计，全生命周期理论，绿色制造，面向制造设计，并行工程  ABSTRACT The traditional casting structural design mainly uses the serial design method. The basic structure of the components is designed first by the components structure designer, and then handed to the foundry technique designers for the foundry technique design and the structural adjustment in the junction. The components structural designers lack the enough knowledge of the foundry technique process while the foundry technique designers can’t understand to the components structural designs overall thought so that communications and exchanges between each other become difficult, the design and the production of the casting comes apart. On the one hand, a lot of wasted time and resources，On the other hand it is difficult to make the performance of castings to be assured，So that the design and manufacture of castings into embarrassment The thesis regarding the casting entire life cycle process, analyzes shortcomings of the traditional casting structural design, explains the importance of the casting life cycle-oriented structural design, with the comprehensive utilization of kinds of theoretical knowledge, including the entire life cycle theory, the green manufacturing, the concurrent design, the manufacturing-oriented design and so on, explores a optimization method not only be able to satisfy with the requirements of the casting structure, but also to satisfy with the request of the manufacturing feasibility, in order to enhance the casting manufacture the feasibility and the onetime success ratio. Key words: casting structural design, entire life cycle theory, green man
