  4. Abstract:
  5. In this paper an experimental/numerical technique is developed for engine mount optimization. The method is general and can be applied to optimize active and passive vibration isolators or absorbers in any mechanical systems or civil structures. Engine mount optimization techniques mostly rely on an accurate mathematical model of the whole vehicle, which in most cases is not available or is too difficult to develop. As a result, the current approach for selecting engine mounts for a vehicle is based upon trial and error which is very time-consuming and expensive. The proposed technique counts upon experimental data for optimization and does not require any mathematical model of the vehicle or its components. The required experiments are similar to the current trial-and-error based experiments performed on a vehicle for mounts selection. The method is evaluated experimentally using a quarter car model and the results corroborate the proposed optimization method
