Summary:The article deals with two alternatives of semi active suspensions of a seat of working machine. A magneto-rheological damper is used in the first case and in the second case the suspension of the seat is a combination of magneto-rheological damper and dynamic absorber. The dynamic absorber is composed from passive elements. In both cases, the dampers are controlled by the well known Sky hook algorithm. The dynamic analysis is focused on the influence of the applied passive dynamic absorber on the reduction of the seat displacements. The passive parameters of the seat suspension and the dynamic absorber were evaluated based on the optimization process using genetic algorithms according the defined minimization function.
