	This article analyses two samples of existing vibration isolation systems. The first sample applies to rubber absorbers, the second, to spring absorbers. The article presents a method of setting the parameters of a second order differential equation describing oscillation movement. The equation parameters were selected on the basis of amplitude measurement and rotation velocity in two representative points – (i) in the resonance and (ii) at the maximum rotation velocity when the influence of the damping factor for the oscillation amplitude can be ignored. Equations of motion simulations were performed and the results were compared with the actual values of displacement and the velocity vibration platform.
