The paper presents the results of the development work on engine mounts. The objective of the present study is to develop idealistic hydromount stiffness and damping characteristics, to minimize the engine induced vibrations over a wide frequency range. A total system level non-linear unconstrained optimizer is used to develop the optimum frequency dependent stiffness and damping characteristics, locations and orientations. Typical engine inertial values and packaging constraints representing a traditional three mount rear wheel drive power plant system, is used in the present study. The front two mounts are hydromounts and the rear mount is an elastomeric mount The study is performed using unit harmonic excitations with a broad frequency range, since the typical engine inertial values are modeled and not an actual engine.
