Low Energy Consumption Hydraulic Techniques

摘要

This report documents the efforts to develop and test low energy consumption hydraulic techniques. Included is a discussion of the efforts to select and analyze a baseline hydraulic system (Phase I) and conduct trade studies on various candidate design approaches which could reduce weight and power consumption (Phase II). In addition, the report discusses the development of a test plan (Phase III) and the results of an endurance test (Phase IV). This program was directed at 8000 psi hydraulic system technology using a nonflammable hydraulic fluid chlorotrifluoroethylene (CTFE) although the concepts developed could be applied to any fluid at any system pressure. The concepts selected for test were variable system pressure, flow augmentation with load recovery valves and overlapped main valves.
