Abstract :
The paper builds ten DOFs mechanical model and mathematical model of the vehicle and equipment, derives its frequency response by Fourier transform, Establishes the off road spectrum as system input, resolve the models with MATTAB software to optimize the location and connection rigidity of the equipment. The study shows that shortening the distance of the equipment from vehicle body center and reduce the connection rigidity can both cut down the acceleration WRMS, that is, to improve its ride performance. The experimental results reveal that the research helps to improve the ride performance and prolong the life and keep integral of the vehicle equipment.
