Abstract

Increasing current vehicle development trends for small, light, front wheel drive vehicles with low idle speeds have been forced automotive industries to use hydraulic engine mounts for further improvement in Vibration, Noise, Vibration and Harshness (NVH) performance of the vehicle. However, with the development of modern vehicle designs such as hybrid vehicles and variable engine management systems which have different operational modes, more sophisticated engine mounting systems are required to effectively response to the each operational mode. MR engine mount is a semi-active hydraulic engine mount, containing MR fluid, that can alter its dynamic behavior as a result of applying magnetic field. In this paper, first, design concept of a new MR mounts is presented and then its dynamic behavior is simulated. It is shown that the MR mount can change its dynamic characteristics as a result of applying magnetic field. Also, it was demonstrated that depending on the strength of the magnetic field, the MR mount can have high stiffness and damping or low stiffness and damping properties, simultaneously.
