Test mechanism for evaluating automatic rotation reliability of rudder sheet rotation actuator cylinder

The automatic rotation reliability evaluation test mechanism comprises an automatic rotation system, a state maintaining and releasing system, a measuring system and a control system, the automatic rotating system provides rotating power and achieves power transmission and comprises a direct current motor, a controller, a dynamic torque sensor, a rocker arm mechanism and a base tool. The state maintaining and releasing system enables the direct current motor and the controller to rotate to a fixed angle and then maintain the state of the rudder sheet rotation actuating cylinder at the angle, and enables the angle to return after the state is maintained for a certain time; the measurement control system comprises an angle sensor and a data collector, and the data collector, the direct current motor and the controller are all electrically connected with the control system. The device can simulate the automatic unfolding and closing actions of the rudder rotation actuator cylinder in the actual working state, ob
