Abstract: Taking the inner plate of certain type of metro vehicle stainless steel vehicle body, using Autoform finite element software, the pattern of how process factors such as lubrication mode, draw bead, blank holder force and die clearance influence the stainless steel inner plate formation is investigated. The results show that the formability can be significantly improved by arranging the PVF film between die and stainless steel plate. The optimal combination of parameters can be obtained by the orthogonal experiment, which could further control and coordinate insufficient drawing and cracks. The optimal setting parameters are the force factor of draw bead being 0.35, the pressure plate force being 300 kN, and the single\|side die clearance being 1.20 mm. Based on the simulated optimal parameters, die design and formation test are conducted, and qualified sample is obtained, which verifies the accuracy of simulation results and effectiveness of controlling methods.
