In the previous paper, the authors proposed a new Cut-off system for vibration control using water and/or functional fluid which acts as a series inertia mass. In this paper, frequency response vibration tests of the Cut-off system installed in one degree of freedom vibration system are carried out using a shaking table. Transmissibility between main mass and base is measured and evaluated. The Cut-off system consists of a piston cylinder, by-pass pipe, and the fluid. It is clarified that the series mass has a large inertia effect which is proportional to the forth power of the inner diameter of the piston cylinder. The experimental results are compared with the numerical analysis, and the effects of vibration isolation are confirmed.
