Abstract
Key on/off vibration on the vehicles comes from many characteristics of powertrain (P/T) system. It is the combination of source and transfer system. So, vibration can be refined by either source reduction or transfer system redesign. In this study, critical factors affecting the key on/off vibration have been identified. An improved example case will be presented from the source and transfer viewpoint. Engine mounting stiffness has been changed by simulation and experiment. The simulation method has been used to assist in the identification of the key design factors of engine mounting system. By determining the rotation angle of an engine mount that is critical factors to powertrain mode and movement, we have reduced key on/off vibration level. The experiment has been performed using an engine mount sample to build the confidence of simulation model. The test results have shown significant improvement of vehicle vibration in key on/off situation.
