Abstract

Aiming at the comfort problem of commercial vehicle cabs, the dynamic model of cab and its mounting system of a typical commercial vehicle was established by using ADAMS software,based on the rigid-flexible coupling multi-body dynamics theory.The accuracy of the model was verified.The DOE optimization test was designed, the stiffness and damping of the cab mount are optimized by simulation analysis, and the test vehicle was improved according to the optimization parameters.Finally, the road test shows that the ride comfort of the optimized commercial vehicle is 9.6% higher than that before optimization, and the vibration isolation performance of the cab is improved.

Key words
