Abstract

An airplane wheel speed simulation device comprises a servo motor, a shifting fork, an airplane wheel hub, an airplane wheel speed sensor, a servo driver, a motion controller and a control box. The servo motor is arranged on the end face of one end of a cover plate, and the airplane wheel speed sensor is arranged on the end face of the other end of the cover plate. One end of a connecting sleeve of the shifting fork is arranged and fixed to a rotor moving shaft of the servo motor in a sleeved mode. The servo motor is coaxial with the shifting fork and the airplane wheel speed sensor. An output connection terminal of the servo driver is connected with an electrical socket of the servo motor through a cable. An input connection terminal of the servo driver is connected with a connection terminal of the motion controller through a cable. On the premise of not changing the work environment of the airplane wheel speed sensor and not damaging an original airborne equipment structure, real wheel speed signals are provided for a brake system, the development period is shortened, the development and test comprehensive level of the airplane wheel brake system is improved, and the airplane wheel speed simulation device has the advantages of being low in cost, high in efficiency, safe and reliable.

Description

technical field [0001] The invention relates to an aircraft wheel speed simulation device, in particular to a device which uses a servo motor to drive a wheel speed sensor in the wheel hub to simulate the actual rotation state of the aircraft wheel. Background technique [0002] When testing the brake system, the brake control box receives the signal of the brake command sensor, the automatic brake signal and the related signals of other systems of the aircraft, which are used to judge the state of the aircraft brake control system and perform brake calculation. The receiver wheel speed sensor, brake pressure sensor According to the calculation result of the anti-skid brake, output the corresponding current signal to the coil of the two-way brake control valve to make it output the necessary brake pressure, so as to realize the anti-skid brake control of the brake system. [0003] When testing the comprehensive performance of the aircraft braking system, the signal of the ai...
