چکیده

Optimization of engine mounts has been performed in several studies; some of them investigated single mount model, some studied mounted engine model, and others discussed on full-vehicle model. The goal of this study is to determine which model is more appropriate for the optimization of Hydraulic Engine Mounts (HEMs). A fullvehicle model is difficult to be modeled, and simulation of the model is time consuming. On the other hand, a simple model cannot express the exact behavior of vehicle system and the optimization may not result in the desired performance of the vehicle; thus, it is desired to optimize the engine mount in the simplest model capable of achieving approximately the best performance. In this study, hydraulic engine mounts are optimized to improve the vehicle ride comfort using a global optimization method called Directed Tabu Search (DTS) method. A full-vehicle model is used to evaluate the optimization results, and to determine whether it is enough to optimize the HEMs in the simplified models to achieve the desired performance, or it is required to precede the optimization for the vehicle model or even a more intricate model.
