摘　　要：压型件作为轨道车辆主要钣金零件组成部分,其毛坯展开精确性对控制成形精度和制造成本有重要作用。采用一步逆算法,基于CATIA/CAA平台开发一套方便用户交互的轨道车辆压型件毛坯展开GUI界面,完成对轨道车辆压型件毛坯的精确展开。以轨道车辆典型压型件小弯梁为研究对象,验证所开发毛坯展开系统的实用性。Profile is used as the main rail vehicle sheet metal parts.The accuracy of the profile unfolding is of great significance to the control of the forming precision and manufacturing cost.One-step inverse algorithm is adopted in it,and a set of friendly blank unfolding GUI interface is developed for users based on CATIA/CAA platform,which is used to complete the precise unfolding of the blank of the pressing part of the rail vehicle.This paper takes a small bend beam of typical rail vehicle as object of study and verifies the feasibility of this system.
