오일 온도변화에 따른 유압시스템 작동특성

Experimental analysis has been carried out to investigate the effect of oil temperature variation on hydraulic system. Hydraulic system performance is largely affected by oil temperature, and there are considerable malfunctions in the system for high temperature conditions caused by heavy load and continuous operation. Oil pressure in the hydraulic system decreases with oil temperature, and its variation rate becomes less steep. Flow rate is also affected by oil temperature. The results in this study will be applicable for optimal design of hydraulic system.
