The governing equations for the motion of machine, floor and dynamic vibration absorber are derived based on the assumption that the floor is considered as a thick plate. In the physical model the isolator is inserted between the machine and floor. The solutions are built up by Galerkin's method. As a harmonic force is applied to the machine, it is found that the secondary damping, i. e. the damping used in dynamic vibration absorber, is better to be as small as possible. In the study it is also found that the primary damping; i. e. the one inhering in the isolator, is of the most important parameter in the vibration control.
