Abstract：

Based on three conditions of draw bead forming theory,distortion calculated result of the curved surface part and the practical plate parameters,the design of curved surface part was simulated stressing on the draw bead parameter setting up by FEA software Dynaform under the conditions of adding draw bead and without draw bead.The draw bead function in deforming the curved surface part was revealed by comparing the simulated results.The theoretical calculation and simulated experiment were proved with each other.At the same time,the experiment validation was made.The results show that the numerical simulation result is consistent well with that of the experiment.This method is simple and intuitionistic in the whole course of machining process.It has a popularized application value for practical production.
