Abstract
A multi degree of freedom type Helmholtz resonator was originally devised in order to attenuate the successive several harmonics of the fixed discrete-frequency pressure pulsation such as those generated by a fixed speed hydraulic pump. However, pump rotational speed is often varied in order to fulfill certain operational cycle in some hydraulic actuator application. Therefore, the development of the present resonator applying to a hydraulic system operated under the variable speed condition is a final goal of this research project. In this report, as a first step, a theoretical feasibility study of the present resonator is mainly described.
