Optimization Method of Suspension System Based on Controlling Transient Shock Motor Vibration

In this paper,the vehicle dynamics model including the motor and the suspension is established,and the dynamic response of the motor under the two typical conditions of acceleration and deceleration is obtained by simulation,and comprehensive evaluation index is established.Based on the design boundary of the motor mounting system modal and decoupling,a vibration optimization model of the control motor considering the mounting stiffness and clearance is established,and the key design parameters of the suspension are optimized.Models and optimization methods can provide an effective basis for the forward design of suspension systems in the early stages of development.
