A Study on Performance of Simplified Vehicle Models inOptimization of Hydraulic Engine Mounts in Comparisonwith FullVehicle

Optimization of engine mounts has been investigated in several studies in which different models, a model of a single engine mount to an intricate fullvehicle model, have been used for the optimization. In this paper two simplified vehicle models and a simple fullvehicle model are used in the optimization of the Hyadraulic Engine Mounts (HEMs) to determine whether optimization through the simplified models can result in appropriate HEMs or the simple fullvehicle model or even more intricate models has to be used in the optimization process. Hydraulic Engine Mounts (HEMs) are optimized through a global optimization method called Direceted Tabu Search (DTS) method in order that the best ride comfort is achieved for the vehicle system.
