Abstract

The invention discloses a load simulator system driven by two motors. The system includes a main control computer, a cooperative motion controller, a torque loading motor, a torque compensating motor, a motor driver, a torque sensor, rotating speed sensors, an angle sensor and a signal acquisition system and the like and the load simulator system is connected with a test steering engine through permanent-magnet eddy current drive systems and a torque transmission device. The load simulator driven by the two motors breaks through a conventional single-motor loading structure and through cooperative motion control and mutual complementarity of the two motors, effects of a redundant torque can be eliminated better and thus loading precision and dynamic responding speed of a torque load can be improved effectively.

Description

technical field [0001] The invention relates to a dual-motor driven load simulator, in particular to a dual-motor driven load simulator which uses a force servo control system to test the performance of a steering gear. Background technique [0002] The steering gear is the executive mechanism for the aircraft to control the flight attitude. The flight of the aircraft according to the predetermined trajectory in the air is to correct the course at any time by controlling the swing of the rudder surface. The performance of the aircraft is directly related to the dynamic quality of the flight process, affecting the flight safety of the aircraft and the quality of completing the flight mission. During the swing process, the rudder surface is subjected to various load moments, including inertia moment, damping moment and hinge moment generated by aerodynamic force. These load moments change greatly during the flight of the aircraft, especially the hinge moment changes with the ...
