To study the constant power characteristics of hydraulic system of a winding belt de- vice,a mathematical model for theoretical analysis ＇was established to analyze the impacts of relevant parameters on system performance,then a simulation model was built to discuss the influences of load fluctuation on system pressure, flow and hydraulic pump motor speed. The experimental table was putted up to test the constant power characteristics of the system. The results show that the system has a fairly good constant power characteristics the simulation model can test the constant power characteristics of the system effectively . Research results herein provide technical support for the im- proved design of the winding belt device hydraulic system.
