Abstract

The invention relates to a large-torque actuator loading testboard comprising a part (3) to be tested, a servo motor (1), an input torque sensor (2), an output torque sensor (4), an oscillating cylinder (5), a servo valve (7) and a hydraulic pump (8), wherein the part (3) to be tested is positioned between the input torque sensor (2) and the output torque sensor (4); the servo motor (1) is connected with the input torque sensor (2); the output torque sensor (4) is connected with the oscillating cylinder (5); the servo valve (7) is positioned between the oscillating cylinder (5) and the hydraulic pump (8); one end of the servo valve (7) is connected with the oscillating cylinder (5), and the other end of the servo valve (7) is connected with the hydraulic pump (8). The invention overcomes the defects that the traditional device for testing wing flaps has a complex structure and can not test a plan by simulating the actual working conditions of a product on the plane, can test the planeby simulating the actual working conditions of the product on the plane and has simple structure and high test accuracy.

Description

technical field [0001] The invention relates to a loading test bench for a large-torque actuator, which is a testing device for performance testing of flap actuators. Background technique [0002] The maneuverability of the aircraft is largely determined by the movement of the flap actuators, which are located on the trailing edge of the wing and which are conventionally actuated by pushrods, idlers and cranks and hydraulically actuated linkages to raise and lower. [0003] The existing device for testing flaps has a complex structure and cannot simulate the actual working conditions of the product on the aircraft to test it. Therefore, it is of great significance to study a high-torque actuator loading test bench that can simulate the actual working conditions of the product on the aircraft. Contents of the invention [0004] The purpose of the present invention is to overcome the disadvantages of the existing test benches, and provide a high-torque actuator loading tes...
