Engine mount vibration level, which is mainly driven by gas and unbalanced inertial forces, is one of the key metrics for the NVH (Noise Vibration Harshness) performance of a vehicle. In addition to gas and unbalanced inertial forces, crankshaft dynamics has also effect on engine mount vibrations. This project is concentrating in including the effect of crankshaft dynamics on engine mount vibrations with the aid of Finite Element Methods and Multi Body Dynamics. Flywheel swirl mode, its effect on engine mount vibration levels and engine mount acceleration for different flywheel configurations will be simulated.
