Abstract:

The purpose of the OSU-MERDC Hydraulic Specification Program is to develop industrially acceptable test procedures and requirement specifications relative to the performance of hydraulic components and systems to facilitate the militarys buy commercial approach. Although the program has been aimed toward components and systems for future 3000 psi operating pressure levels, it was intended that the test procedures be applicable to any pressure level. The report presents a detailed account of the experimental verification part of the hydraulic noise study. Test procedures for hydraulic component noise, developed under this contract, are presented and experimentally verified. The preliminary results of a measurement survey of airborne pump noise, supported by an extension of the contract, are presented and compared with published sound power levels for pumps. Specific recommendations are made for continuing the effort to understand and control hydraulic noise.
