| Abstract: | Based on the dynamics of gear system and theory of nonlinear vibration,considering characteristics of the gear backlash and time-varying mesh stiffness in gear transmission system of tracked vehicle,the nonlinear vibration model of single degree of freedom gear system is developed.The nonlinear vibration characteristics on condition of different shift process are analyzed by using numerical simulation method,and studied in some variable parameters.The conclusions have indicated the dynamics performance and given powerful evidence for the more multiple degrees of freedom nonlinear vibration studying in the gear transmission system. |
