| Abstract: | ROPS dynamic simulation modeling method and roll-over test method based on the whole vehicle were presented.Taking the model ROPS of wheel loader′s rolling at a 30° slope as an example,the simulation results and the laboratory results were compared.The results show that the modeling method is reasonable,and the impact force,plastic hinge and the discipline of energy absorption in the process of collision and roll-over were given. |
