EFFECTS OF PARAMETERS OF CAB’S ISOLATION SYSTEM ON RIDE COMFORT FOR A SINGLE-DRUM VIBRATORY ROLLER

The purpose of this paper is to analyze the effects of parameters of cab's isolation system on ride comfort for a single-drum vibratory roller. To analyze and evaluate the its effects on vehicle ride comfort, a half vehicle dynamic model of a single-drum vibratory roller is established under the different operating conditions. The parameters of cab's isolation system such as stiffness and damping coefficients are respectively analyzed based on two objective functions according to the international standard ISO 2631-1. The analysis results indicate that cab ride comfort is greatly influenced by the parameters of the isolation system. The vehicle ride comfort is going to be worse with the increase of the stiffness coefficient of cab's isolation system. However, the vehicle ride comfort is improved with the increase of the damping coefficient. Finally, the optimal parameters of cab's isolation system are proposed through the analytical results under different operating conditions.
