Problems solved by technology

There are many disadvantages and limitations. First, the dragging wheel of the tire mopping device is a great wear and tear on the wheel, so that each test will have an impact on the life of the tire. Second, the dragging speed is rough and can only be adjusted to a certain extent. Judging whether the anti-skid system is working or not
Third, the test items are limited, and the delay time of the anti-skid landing protection, the release speed of the brake lock signal and other items cannot meet the test requirements.

Description

technical field [0001] The invention relates to a detection device for an aircraft anti-skid braking system, in particular to an in-situ detection device for an anti-skid electric control system. Background technique [0002] In order to prevent the aircraft from skidding or deviating from the runway during the braking process of the landing process, an anti-skid braking system is installed on a certain type of trainer, which includes two wheel rotation frequency sensors, an anti-skid control component, and two electro-hydraulic valves. The working relationship is: the wheel frequency sensor senses the speed of the aircraft wheel, and the various changes in the speed are transmitted to the anti-skid control part in real time. The electro-hydraulic valve is turned on or off to realize the function of brake lock or release, to eliminate the non-allowable skid during wheel braking and to prohibit wheel braking when the pilot brakes in advance (that is, to realize the landing pr...
