Steady-state forced vibration, free and transient vibrations of the system with elastically supported damper whose damping is proportional to the square of the velocity are analyzed by the analog-computer. The results showed that ; (l) the amplitudes obtained by the equivalent viscous damping method are smaller in some degree than those by the analog-computer, (2) the magnification factor of the system excited by motion is not identical with the transmissibility of the one excited by force, (3) the optimum damping value derived from the equivalent viscous damping method is approximately true, (4) an optimum value of damping for the free vibration exists, which lies far from that for forced vibration, (5) the damping character of the free vibration is not so good especially in the region of the small amplitude, (6) the response to a sudden disturbance is different entirely from that of the viscous damping system, (7) the results of the experiment which was formerly carried out on the model system and the vibrating table coincide fairly well with those of the analysis.
