Several concepts of the stand designed for experiments carried out on linear magneto-rheological (MR) dampers are introduced in the paper. The stand is constructed under assumption that analysis of vibroisolated object motion is limited to the plane motion. There have been analysed variety of the stand designs. Their common feature was the ability to achieve two independent kinematic excitations, that have the form of vibrations transmitted through the investigated controlled vibroisolators to the container filled with medium. Advantages and disadvantages of the particular designs are considered in relation to the given entrance assumptions and project limitations. The last complex solution was done as a reasonable selection taking into consideration the quality coefficients of undertaken tasks that mainly refer to data acquisition and control. There have been given elements of mechanical system dynamics analysis that form a database for estimation of parametric sensitivity of the whole system: investigated object supported on vibroisolators - system of shakers - instrumentation.
