The vibration system treated in this paper is of single degree of freedom, which consists of four dampers and a mass. Visco-elasticity material for the damper is urethane resin. The vibration transmissibility and loss factor of the urethane resin are measured by forced vibration of the damper system. The transmissibility are about 2.4∿3.0 in the resonance of the vibration system, and the effect of the exciting displacement amplitude appears slightly in the transmissibility. The loss factors calculated by the transmissibility are about 0.35∿0.45,and the effect of the static stress appears clearly in the loss factors.
