For lower vibration gear design, demand for multi degree-of-freedom (hereafter, DOF) vibration analysis is increasing. But damping parameters for a geared machinery is difficult to measure directly because its excitation force with gear meshing cannot be measured. This paper introduces an experimental identification method of damping coefficients of 2-DOF vibration model for a power transmitting gear system as a basis of multi DOF vibration analysis. In the proposed method, modal analysis was performed with measured vibration response and we have obtained 2-DOF damping coefficients, rotational and transverse vibration, without any trial and error process. For this purpose tubular shaft was used so that the damping coefficient can be changed by putting additional center core rod coaxially to give frictional losse. And the analyzed damping coefficients are verified experimentally with a gear test rig in which the damping effect can be intensionally changed.
