Paper Abstract

Two multi-body car models with rubber mounts and without rubber mounts have been built up to research how the suspension rubber mounts impact ride comfort. The comfort mount was used to simulate the impact process. Two scenarios have been set up, and time integrations have been performed to get the acceleration-time histories of seat surface in the x-, y-, and z-direction. A MATLAB program was compiled to calculate the weighted RMS acceleration. For the first scenario, the relative difference of weighted RMS acceleration between the car models with rubber mounts and without rubber mounts gradually decreases as the road roughness increases. For the second scenario, the relative difference increases as the driving speed increases. The conclusion shows that the change of driving speed or road roughness impacts ride comfort. Especially for high driving speed this impact is quite obvious.
