When the road conditions of the vehicle are poor,the driver not only needs to withstand the impact of vibration,but also severe instantaneous impact force.To avoid sensitive frequency bands in the horizontal,horizontal,and vertical directions of the human body,and to reduce vibration intensity.Firstly,as the dynamic model of the damping device is a multi degree of freedom,multi parameter coupling,and nonlinear complex sys-tem,the matrix transformation method is used for decoupling and modal analysis of the damped system;Then,conduct vibration response analysis on the three-dimensional damping device,and simulate the system by apply-ing instantaneous impact forces in the X,Y,and Z directions of the moving platform.The simulation results show that the damping platform has good damping effect.Due to the coupling of the three branches of the 3-PCR parallel mechanism,the low-frequency vibration will maintain for a period of time and then tend to stabilize.
