Aiming at the discrete problem of the electric machine-brake complex of an actuator when unlocking under accel-eration environment,mechanism analysis,finite element simulation and test verification are carried out,and it is concluded that the reason of unreliable unlocking is that the electromagnetic force cannot completely overcome the load increment gen-erated under acceleration environment.Through the integrated structural design of the housing and the end cover,the effec-tive electromagnetic volume of the brake is improved,and the requirements for the electromagnetic force and threshold cur-rent are met by increasing the ampere-turns and adjusting the diameter of the enameled wires.The mandatory inspection point is set under normal environment to ensure that the brake can be unlocked reliably in the acceleration environment.
