Abstract:
The anti-collision side beam inside the car doors is a key component to improve the safety. Foreign automobile companies use ultra-high strength steel plate to manufacture it. However, it is very difficult to form at room temperature, so usually it is made by hot stamping but the cost is high. The use of FEM software Dynaform in simulating and optimizing the forming process at room temperature is described, and the influence of temperature on internal organizational changes of the ultra-high strength sheet is mainly studied. By comparing the simulation result and real sample, the effect of addendum on stamping and springback is researched and convex roofs in the addendum is added to optimize the surface. It is helpful for manufacturing the relative high strength steel parts.
