Abstract: There is a certain oblique angle between the steering axis of the steering wheel of a special type of vehicle with the vertical direction clamp. In order to test the performance of the steering wheel when there is resistance to turn, this paper designs an electric torque loading test-device for the inclined axle, and analyses the basic working principle, main technical problems and system structure of the electric load simulator. According to the characteristics of the tilt axis moment loading test-device, the generation mechanism of the main interference moment is obtained. By analysing the mathematical model of disturbance torque, a feedforward compensation control method based on the principle of structure invariance is proposed. The simulation results of MATLAB-Simulink show that the design strategy of the tilting axis electric torque loading test-device is effective, and its control method can effectively suppress the influence of interference torque and improve the accuracy of torque loading. This paper has technical innovation and practical application value in the field of aerospace special vehicle driving and steering test research.
