| Abstract: | 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. |
