In this paper, an analytical rigid body model of an engine mounting system was identified using experimentally obtained rubber stiffness and modal parameters. Forced vibration test confirms the reliability of the model by comparing the analytically obtained rigid motion with the test results. Using the confirmed model, mounting locations and angles of the mounting system were reanalyzed to minimize the transmitted forces through rubber mounts at idling speed. The analytical simulation shows that the transmitted forces can be reduced significantly as changing only the mounting locations and angles.
