【 摘 要 】

Aimed at obtaining the influence laws of parameters on the simulation results with the finite element method, this paper research on these parameters. The results show that the hourglass mode, time step and the coefficient of friction have great influence on the simulation result. Finally, the general effects of these parameters on the simulation results are obtained.
