The Research of Hydraulic Pressure Intensifier for Use in Electric Drive System

Abstract

This paper discusses the proposal of use of a hydraulic amplifier as a drive system's supporting element - for example, the drive of work equipment in unmanned ground vehicles (UGVs) is powered by electricity. Such a solution can provide very high forces on actuators of UGV (cutters, spreaders, hydraulic wrenches, and chisels) with relatively low electricity demand. The experimental tests of the amplifier in laboratory conditions for various power supply and load configurations of the amplifier are presented. The obtained test results allowed to estimate its usefulness in the solutions proposed above and to determine the further path of detailed research for selected electrical system solutions equipped with hydraulic amplifiers.
