Abstract : Specifically the human perception of the dynamic comfort of a seat is an area that is of importance to automotive manufacturers for a market becoming more and more competitive and sophisticated. A major portion of the vibration experienced by the occupants of an automobile enters the body through the seat. To date significant attention has been paid to the static comfort of seats while work on dynamic seat comfort is limited. Semi-active control systems are becoming more popular because they offer both the reliability of passive systems and the versatility of active control systems without imposing heavy power demands. In particular, it has been found that magneto-rheological (MR) fluids can be designed to be very effective vibration control actuators, which use MR fluids to produce controllable damping force. The objective of this paper is to design and study a driver seat suspension system model with an MR fluid damper under harmonic excitations with finite element (FE) analysis. We have studied the response of MR damper to vibration, which plays a key role in determining the dynamic comfort.
