Description
technical field [0001] The invention relates to the technical field of steering gear, in particular to a comprehensive stress loading device for steering gear. Background technique [0002] The steering gear is an important servo mechanism of the aircraft. It is the actuator of the ruddersystem and drives the deflection of the rudder surface to control the flight attitude of the aircraft. During the flight of the aircraft, the steering gear will be subjected to various stress environments such as vibration, temperature, bending moment and torque while driving the rudder surface to deflect. The traditional loading assessment test method for the steering gear is basically a single stress loading test. A set of test devices apply single vibration, temperature, bending moment or torque stress to the steering gear respectively, and test the performance indicators of the steering gear in a single stress environment. [0003] However, the disadvantage of the assessment method of ...
