摘要
开发了一个曲轴TR镦锻模具CAD/CAE系统,该系统的功能包括锻件设计、毛坯设计、模具设计、图纸输出以及与CAE软件的接口。介绍了系统开发的流程及方法。系统开发的关键技术包括建立参数化图库、图形自动绘制和成形过程模拟等。作为应用实例,采用该系统完成了某型号曲轴的全部设计流程,通过对曲轴锻造过程的有限元模拟优化了毛坯尺寸,从而验证了系统的可行性。
A CAD/CAE system for TR forging die for crankshaft was developed, which included the functions of forging design, billet design, die design, output of the drawings and the interface between CAD and CAE software. The development process and method of the system were introduced. The key development techniques include establishment of the parameterized part library, automatic generation of the drawings and simulation of the forming process. As an example, the whole design process of a crankshaft was carried out by the system and the billet dimensions were optimized by finite element simulation of the forging process, then the feasibility of the system was verified.
