In the present study, an analytical model with six degrees of freedom is identified using the modal parameters obtained from the exprimental modal analysis. It's structural parameters, i.e., mass moment of inertia of the engine block and stiffness of the rubber mounts, are estimated using the condition that they should satisfy the undamped eigenvalue problem.
For the identified dynamic model, mounting locations and inclination angles are changed to minimize the transmitted forces of the engine onto the frame at the idling speed. The simulation study shows that by adjusting the engine's mounting system properly, the transmitted forces are reduced significantly.
