| Abstract: | Spot welded thin-walled beam play an important role in vehicle crash. It is a typical energy absorbing structure during collision. In this paper, a finite element model for analysis is established. At the same time, contrasting the experiment result with the computer simulation result, the validity of simulation is indicated. Then using the finite element model, the contact friction in crash simulation is discussed and the choice of friction coefficient is advised. |
