Abstract

The present invention provides a permanent magnetic brake unit electromagnetic suction force test testing device. The device comprises: brake stators (1), a first support platform (2), height regulation rods (3), a second support platform (4), a guide bar (5), a brake rotor (6), a mass block guide rod (7) and mass blocks (8). The brake stators (1) are connected with the first support platform (2); the first support platform (2) is connected with the second support platform (4) through the height regulation rods (3), and the height regulation rods (3) regulate the levelness of the first support platform (2) to regulate the levelness of the brake rotor (6); the lower end of the mass block guide rod (7) is connected with the mass blocks (8), and the lower end faces of the mass blocks (8) are in interference fit with the upper end face of the guide bar (5); and the guide bar (5), is located at the upper end face of the brake rotor (6) to conduct vertically downward loading force to the brake rotor (6).

Description

technical field [0001] The invention belongs to the field of brake testing and relates to a test device for testing the electromagnetic attraction force of a permanent magnet brake. Background technique [0002] The brake is the key component of the channel switching and fault isolation of the dual-input channel electromechanical actuator, and the performance of the brake is directly related to the function realization of the actuator. The principle of the permanent magnet brake is to unlock when the power is on, and to brake when the power is off. Among them, the main parameters affecting the performance of the brake are the electromagnetic attraction force of the permanent magnet and the material performance of the friction plate. The electromagnetic attraction force is mainly the attraction force of the permanent magnet of the brake on the friction plate. Through the attraction force, the friction plate and the brake stator are attracted together to generate friction tor...
