| Abstract: | NVH Power train is a combination of systemic issue which includes car noise,vibration and harmonic vibration roughness.It involves interaction of multiple systems of vehicles.We focus on setting up power train and classic vibration model based on the existence of vibration of power train and suspension subsystems.Under the simulation of MATLAB/simlink,NVH power train mounting system performance mainly concentrates on the both directions of vertical and rotate crankshaft which greatly affect riding quality o... |
