Simulation Method for Vibration Isolation Performance of Vehicle Powertrain Mounting System
摘要
Abstract
The properties of vehicle’s noise vibration harshness(NVH) was affected by the vibra-tion isolation of powertrain mount system .Using the mechanism of vibration isolation to conclude the vibration transmitting rate expression which was defined by RMS ;based on the mechanism of double layer vibration isolation ,a 6-DOF model of a powertrain mounting system and a 12-DOF full vehicle model including the car frame were built respectively ,the inherent characteristics and frequency re-sponse of the two models were compared by the simulation analysis ;and under the idling conditions , acceleration response of the powertrain mounting system was studied;the vibration transmitting rate curve of the mounting points was obtained eventually .The results show that the full vehicle model can response the vibration characteristics of a powertrain mounting model and get the vehicle’s vibration i-solation transmitting rate at the same time .关键词
