Development of Engine Mount System for Low Frequency Vibration Improvement

Recent trend towards the lighter car body and the higher performance of powertrain makes NVH engineers do much work. The vibrations at idle, engine starting and gear shift are critical because those are easily perceptible phenomena of car at idle. The enhancement can be obtained through the optimization of engine mount system because those are mainly caused by engine torque fluctuation. To shorten the development period, automotive engineers are willing to do extensive cooperated application of CAE with experiment in the process of car development. In this paper the strategy of integration of CAE and experiment is introduced to develop engine mount system efficiently at initial design stage.
