Abstract

The vertical variable-speed motion of the vehicle passing the speed bump makes the electric powertrain in a non-inertial system. To study the dynamic characteristics of electric powertrain under non-inertial conditions, the powertrain and tire dynamic model are established. The additional inertia force is derived. It is involved in the dynamic equation in the form of force excitation. The influence of inertia force on the dynamic response and load characteristics of the system is analyzed. Furthermore, the influence of speed bump height, vehicle speed, and tire stiffness on the bearing force is studied. The results show that the equilibrium position of gears is greatly offset due to the influence of non-inertial system when the vehicle passes the speed bump. And the bearing support force and vibration response are significantly increased. The research results provide theoretical support for vibration and noise reduction and dynamic load calculation of electric powertrain.
