The automotive trend is now days switching towards less weight, cost effective and power efficient powertrain. Consumer’s expectations from comfort and NVH point of view is rising day by day. The NVH performance of a powertrain is mainly affected by the powertrain mounting System. In design and development of a new vehicle, the mounting of the powertrain (engine-transmission assembly) receives special attention. The powertrain body is the major concentrated mass in the vehicle Which if not adequately confined and quarantined, it will result in poor NVH characteristics of powertrain. In this work a powertrain mounting System of three-cylinder engine, which is transversely mounted, is analyzed. A correlation between two different simulation techniques has been established. Passive mounts are being assessed throughout the investigation. A multi body simulation approach is employed for the modelling and simulation of powertrain mounting system.
