The model is comprised of the general rigid-body equations considering apparent mass and the modeling method of suspension system based on the assumption of "equilibrium points".
Marine diesel is simulated by the upper massof the system. Proper positions of secondary vibration source are chosen and some points on the lower mass are chosen for error evaluation.
