In this work, the dedicated test stand was applied to investigate the human body–vehicle seat system. The particular signals were measured by accelerometers placed on the seat and the human head. The horizontal vibrations were applied as the input to the system. As an alternative to the classical Fourier approach, the wavelet transfer function was introduced to describe the effectiveness of particular seat suspension. The human head reaction was investigated as the system output.

This research aims at the vibration control of vehicle seat suspension system. A three degree of freedom quarter vehicle model is used for semi-active control system in which a magnetorheological damper (MRD) is installed at the position between the vehicle body and the seat. A fully active linear quadratic regulator (LQR) control strategy is used to determine the optimized control force which is then matched by MRD to compute the semi-active control result. Computation result proves that semi-active control with MRD can alleviate the vehicle seat acceleration to improve ride comfort.

Vibration of vehicle system is a typical vibration of multi-degree freedom. The damping performance of multi-degree freedom seat suspension is important to ride comfort of vehicle occupants. Based on the multi-dimensional movement principle of parallel mechanism, it is built a new vehicle seat with 3-DOF suspension. It is Established a kinematics model and then analyzed the theory of the displacement of the parallel vehicle seat system. Finally, using ADAMS software to build the simulation models of seat suspension, it is showed that the seat vibration system has a good effort on vibration reduction.
