摘要: Energy efficiency has become a major research issue in all fields of engineering. Opportunities of utilizing electric servo drives in the control of hydraulic lifting systems directly by an electric-servomotor-driven hydraulic machine and enabling energy recovery in them are studied. In this paper, the modelling and testing of an electro-hydraulic lifting and lowering system and a forklift with two lifting zones are carried out and analyzed. The efficiencies and energy-saving ratios of the experimental drive system are determined for the …
