Optimization and Springback Control of Ultra-High Strength Steel Door Beam Forming Process
The door beam inside the car door is an key component to improve the security of passengers, most great automobile manufacturing companies use ultra-high strength steel plate to manufacture it，however, it is very difficult to form in room temperature，so commonly it is made by hot stamping but the cost is too high. This article gives a solution to deal with this problem by the use of FEM software in simulating and optimizing the forming process of one kind of ultra-high strength steel door beam in room temperature, and main study is in the influence of temperature on internal organization changes of the ultra-high strength sheet and springback by comparing the simulation result and real sample, and meanwhile convex roofs are added in the addendum to optimize the surface. It is helpful on how to design die face in manufacturing the related ultra-high strength steel parts.
