impact forces maximum indention actuation duration hyper-elasticity elasticity elasticity-plasticity Hertz theory
The non-linear damping-spring model based on Hertz theory is adopted to simulate the impact contact process of two special shape and material components with the elasticity,the hyper-elasticity and the elasticity-plasticity.The simulation results are 50% that of the finite element analysis.According to the finite element computation result,the non-linear damping-spring model is corrected,and the corrected expression of the impact force,the maximum indention and the actuation duration of the two components are obtained.The results show that the error between the corrected model and the finite element computation is less than 5%,and the impact parameters can be obtained easily through the corrected model.The model can be used to describe the impact process of two components.
