Abstract

The invention discloses a steering engine service life ground verification system and verification method, the verification system comprises a steering engine, a transmission part and a control surface simulation device, and the moving end of the steering engine is connected to the control surface simulation device through the transmission part; the control surface simulation device is used for simulating inertia and moment borne by a real control surface; the external potentiometer is used for measuring actual measurement data of the output quantity of the steering engine, and the precision of the external potentiometer is larger than that of a built-in potentiometer integrated in the steering engine; the upper computer is used for sending a control surface instruction to the steering engine so as to control the steering engine to drive the control surface simulation device to move; the control surface instruction comprises a rotation angle of a control surface; receiving measured data measured by the external potentiometer; and whether the difference value between the measured data and the rotation angle exceeds a threshold value or not is judged, and if yes, it is judged that the steering engine reaches the service life.

Description

technical field [0001] The invention belongs to the field of aviation testing and support equipment, and in particular relates to a ground verification system and verification method for the life of a steering gear. Background technique [0002] The steering gear is an important servo mechanism of the aircraft flight control system. It is the actuator of the rudder system and drives the deflection of the rudder surface to control the flight attitude of the aircraft. The performance of the steering gear is directly related to the handling performance of the aircraft. [0003] At present, most of the life tests for steering gears are long-term no-load test evaluations on the ground or tests with elastic loads. In the existing steering gear performance test, the influence of the mass and torque of the rudder surface has not been fully considered, and the load generated by the aerodynamic force has not been simulated at the same time. Simulate the environment of the rudder sur...
