In this paper, the modelling process and control strategy of the semi-active seat suspension with magneto-rheological damper (MR) is presented. The proposed system should protect the working machines operators against vibration in horizontal direction. The control algorithm mimics the desired force that might be actively introduced into the seat suspension. The model parameters are determined experimentally as a function of the control current. The elaborated system is tested by using the electro-hydraulic shaker that generates vibrations of the semi-active seat suspension with seated human body. The power spectral densities and the transmissibility functions are presented as the results of simulations and measurements. In addition, the transmissibility factors and the maximum relative displacements of suspension are evaluated for both the conventional passive seat suspension and the semi-active system with MR damper.
