Abstract
This paper describes a simulation method for analyzing the NVH issues of vehicle transmission system via MBS approach. By substituting the real vehicle parameters into the simulation, the built MBS model was used to simulate the dynamical properties of power-transmission system. After verifying the feasibility of this simulation method via a direct measurement, the NVH performance of the built vehicle model was improved through sensitivity analysis and parameter optimization.
