When the landing gear system of civil aircraft is in the fault state, the backup release system will be enabled, in this case, the landing gear system and the landing gear cabin door are in no-driven mode, and its extension only relies on gravity. In this process, if the static friction force between the landing gear tire and the landing gear cabin door is too large, the landing gear system will be stuck and fail to extension. It’s important to measure the static friction in early design to avoid this. In this paper, a simple and high efficiency test bench is designed to measure the static frictional force coefficient between the tire and door. There is only one parameter measured in the test bench, based on which the test bench is high efficiency, high repeatability and high precision of the test results.
