An experimental method to analyze the damping characteristics of hydraulic components is proposed in this report. By using our 3-mirophones Method, the absorption coefficient, propagation constants and the characteristic impedance of the component in the liquid-filled piping systems were measured. Experiments were conducted on the thin-tubes in the side branch pipe. Moreover, by using these damping characteristics of the component, we analyzed the pressure pulsation of the total hydraulic system. From the results obtained, this method is useful to evaluate the pulsation characteristics of the hydraulic systems.
