Vibration analysis based on full multi-body model for the commercial vehicle suspension system

Abstract

Based on the characteristic of a type of commercial vehicle, a multi-body model of its full suspension system with twenty Degree of Freedom (DOF) was established in MSC. ADAMS. After evaluating relative condition parameters such as stiffness and damping index on the simulation model, the effects of outside exciting on the suspension system have been worked out numerically. The harmonic response of the mass center of the seat at model coordinate space provides reference for the general performance of the suspension system which enable the future design improving.
