【 摘 要 】

The nonlinear finite element model of the top guard is established. The contact arithmetic and loading method are discussed. The time-deformation curves of loading center are gained. The falling object experiment is carried out on the test equipment. The simulation results are accord well with the experimental ones. The dynamic simulation of the hydraulic excavators' top guard provides the basis for the structural design.
