Content
Hydraulic systems pose a particular problem for noise control. Due to the high speed of sound in hydraulic fluids, components typically designed to reduce fluid-borne noise can easily exceed practical size constraints. This paper presents novel solutions to creating compact and effective noise control devices for fluid power systems. A hydraulic silencer is presented that utilizes a voided polymer lining in lieu of a pressurized bladder. Theoretical modeling is developed which predicts device performance and can assist in future design work. Experimental results are presented to demonstrate the performance of the device. Both voided and non-voided liners are tested to show the effect of the voiding on the performance. In addition, theoretical modeling and experimental results are presented for a prototype Helmholtz resonator that is two orders of magnitude smaller than previously developed devices.
