Many researches have tried to find causes of engine and vehicle vibrations and reduction methods by considering that the engine unbalance condition and inputs from bumpy roads are vibration sources and would reduce the vehicles performance. However, there is a lot of unknowns in modeling and the simulation of vibrations. One of them is active mount cooling and side effects of cooling on its structure and performance. This paper defines a new active multi-compartment mount with a cooling capacity and explains reasons for the improvement of thermal conditions by considering this fact that the heat generates in active mounts and reduces their performance. Vibration modeling of the system is presented and effects of parameters on results of the new chamber have also been studied. As a result, using the middle duct and adding a new compartment are proposed as a solution to improve cooling conditions. The new vibration model and the control algorithm had no adverse effect on the mount. Finally, an appropriate control strategy is proposed by the control algorithm of the system.
