| Abstract: | Spot welded thin-walled beam plays an important role during vehicle crash.It is a typical energy absorbing structure during collision.In this paper,a finite element model for analysis was established.At the same time the computer simulation result was compared with the experiment results. Thus the validity of simulation is indicated. Then using the finite element model,the time step in crash simulation was discussed and the efficiency of simulation was improved. |
