Abstract:

The material experiment about mechanical characteristics and microstructure were carried out. This is the base of application and side crash simulation of hot forming HSSS in car body. In order to improve the side crashworthiness of car body, the side structure of car body is substituted with hot forming high strength steel material. The side crash of changed car body is simulated to different combination of change. The results indicate that the side crashworthiness of car body is improved by application of hot forming high strength steel sheet.

Key words: hot forming, high strength steel, car body, side crash
