Background
The civil aviation aircraft installs braking system on every main wheel, because the interval between the aircraft both sides undercarriage is great, when the brake pressure of both sides wheel exists the difference, can lead to the difference of both sides braking effect to make the aircraft deflect to the stronger one side of braking effect, be unfavorable for the manipulation of aircraft, under the extreme condition, can lead to blowing out or even rush out the serious consequence of runway. The wheel speed meter arranged on the airplane wheel is used for measuring the rotating speed of the corresponding airplane wheel, and the measurement result is used for feeding back the locking condition of the airplane wheel under the braking action. After certain calculation is carried out on the measurement result, the calculation result is used for adjusting the brake pressure of each airplane wheel so as to ensure that the brake force on two sides of the airplane is balanced.
When relevant system test work is carried out, the airplane wheel is in a static state, and special equipment is needed to directly drive the wheel speed meter so as to simulate the state when the airplane runs. At present, the tachometer driving component with the part number of G5-5M0-319 and 0000 purchased by the civil aviation maintenance unit is produced by an airbus company. The main components of the system comprise 1 control box, 2 drivers, a bracket and 1 group of cables. The equipment drives a wheel speed meter through a direct current motor, and functions of switching of the equipment, reversing of the motor, adjusting and displaying of rotating speed and the like are achieved on a control box. When the driver support is used, the driver support is fixed on the airplane hub by using the self-provided clamp, the two drivers and the airplane ground service power supply are respectively connected with the control box by using cables, the operation is complicated, and the cables are too long and are easy to damage. In addition, the rotational speed regulating function of the device is open-loop control, and the rotational speed must be regulated in an operating state, and if the regulation is not proper, the aircraft components can be damaged due to the excessively high rotational speed.
