This paper derives the mathematical model of the disturbance torque in loading system of electrohydraulic load simulator, analyzes all the factors of affecting the disturbance torque and simulates the effects of the object's angular displacement and total leakage coefficient of loading motor to the disturbance torque. According to the result of theoretical analysis, the paper puts forward the methods to eliminate the disturbance torque by mounting interconnected pore. between two cavities of loading motor and synchro-compensation. Finally, the experimental results prove that the methods presented by this paper can effectively eliminate the disturbance torque of electrolivdraulic load simulator.
