Abstract：

The numerical simulation method with the Autoform software of metal tube product's forming process of HongQi-C131car was presented. The main quality problems were analyzed and the solution for modification was designed. According to the simulation result with Autoform software，the solution that added bead to the lower die resolves the concave and controls the springback in the tube product's forming process，so the design and assembly requirements are met.
