[0002] The front landing gear refers to a component of the landing gear, which is a ground support component installed under the nose of the aircraft. The friction plate is used to produce braking effect when the tire rubs against the friction plate after the front landing gear is retracted. The friction plate will be worn after long-term use. A friction plate wear test tool is required to perform a wear test on the friction plate to ensure the quality of the friction plate.

The wear degree of the friction plate is judged manually, and the judgment error is large. Therefore, those skilled in the art provide a friction plate wear test tool to solve the problems raised in the above background technology. Utility Model Content
