Description

technical field [0001] The invention belongs to the technical field of aeronautical testing and testing, and relates to a servo mechanism testing device, in particular to a servo mechanism deflection angle automatic recognition testing device and method. Background technique [0002] During the production and development process of the servo mechanism, in order to fully simulate the stress state in the working process to ensure the reliability of product quality, a large number of tests and experiments are required; the most important test is the load test of the servo mechanism. [0003] At present, the commonly used test method is to connect the servo mechanism with the small moment elastic torsion bar through the tooling, apply a certain control signal through the tester to control the rotation of the steering gear, and judge its performance by manually reading the deflection angle of the servo mechanism. However, because this method relies on manual readings, there is a ...
