TECHNICAL FIELD

[0002] The traditional electromechanical actuator loading bench mainly realizes the loading of the actuator through a rotating rocker arm. Due to the existence of the rocker arm, the main shaft of the loading part and the main shaft of the electromechanical actuator are vertically arranged. Therefore, no matter whether the loading part is vertically arranged on the ground or designed in parallel with the ground, due to the existence of the rotational inertia of the rocker arm, the rotational inertia of the rotating part of the whole system is much larger than the rotational inertia of the real electromechanical actuator, which increases the dynamic load and changes the acceleration performance. Finally, the power level of the test bench is much larger than the power level of the electromechanical actuator itself, so the system performance of the final test bench deviates from the performance of the real system where the electromechanical actuator is located. Moreover, due to the vertical arrangement, the space occupied by the loading bench is large. SUMMARY
