In this study, the air suspension is newly applied to the engine mounting layout for getting the significant vibration isolation effect. In this case, a genetic algorithm (GA) is also applied for the optimization of many parameters, calculations of stiffness matrix and inverse stiffness matrix to prevent the coupled vibration of lateral and rolling modes and to obtain the displacement of each mounting point. As a result, inexperienced engineers can easily obtain the optimum engine mounting layout in a minute. By the confirmation test of FEM (finite-element-method), the engine lateral vibration level at 25 Hz dropped below 1/10 and its effect was significant. On the other hand the vertical displacement is too big, and its value should be reduced below 10 mm by the mechanical way such as an additional stopper or the higher spring rate at the big torque input.
