摘　　要：The theoretical model of docking impact dynamics based on flexible cone is presented according to Foppl-von Karman＇s non-linear differential equations and Hertz contact theory. Finite diflerence technique is used to solve this theoretical model. Results of the theoretical model show good agreement with the experimental and ANSYS/LS-DYNA simulation results. In ad- dition, the influence of flexible cone parameters on impact process is discussed based on theoretical model systemically.The theoretical model of docking impact dynamics based on flexible cone is presented according to F ppl-von Kármán’s non-linear differential equations and Hertz contact theory.Finite difference technique is used to solve this theoretical model.Results of the theoretical model show good agreement with the experimental and ANSYS/LS-DYNA simulation results.In addition,the influence of flexible cone parameters on impact process is discussed based on theoretical model systemically.
