摘　　要：随着计算机辅助设计(CAD)技术的发展,三维CAD逐步替代传统设计手段,成为产品研发设计的主要工具。介绍了数字化三维CAD在上海国产化A型地铁列车项目中的运用;以各种零部件设计为例,描述了骨架设计、零件设计、装配设计等三维CAD设计流程;并叙述了三维CAD在轨道交通车辆设计领域中的优点。With the rapid development of computer aided design （CAD） technology, three- dimensional CAD has become the main tool instead of traditional CAD in the fields of product research and development. This paper introduces the application of digital three-dimensional CAD in the project of shanghai homemade type A metro train. In various parts of the design as an example, this paper describes the three-dimensional CAD design process including skeleton design, part design, assembly design, etc. This paper also summarizes the advantage of three-dimensional CAD in the realm of rolling stock.

关 键 词：三维CAD 骨架设计 零件设计 装配设计 轨道交通车辆
