Damping is a phenomenon of the gradual conversion of kinematics energy to heat. In general, damping action is too difficult to evaluate with certainty. When a member vibrates in a fluid such as air, water or oil, it is virtually impossible to calculate the amount of damping caused by the fluid motion in an analytic method. Nevertheless, it is possible to find analytic solutions in certain particular cases, mostly when the flow pattern is laminar. In this paper, we propose equations to be used in the calculation of damping in a few dampers such as the oil-film damper, oil damper and air damper. The effect of the frequency of the vibratory member on the damping may be considered in the analysis. Furthermore, it is necessary to give full consideration to the mass effect of oil and to the compressibility of air.
