Abstract：

By means of finite element numerical simulation, the forward and reverse drawing process of the automotive soleplate component part was studied, and the properties of sheet metal forming in different strain paths conditions were discussed. The results indicate that the stamping forming quality is greatly influenced by the change of strain path and the stamping forming quality can be improved by the strain paths of forming dangerous point. Convex hull height of 33 mm, corner radius of 20 mm are determined as optimized forming plan for automotive soleplate component parts, and automotive soleplate component parts forming performance can be fully used to achieve better forming qualities in the plan. Complex shape parts forming and multistep forming can be well predicted using the finite element numerical simulation method.
