Abstract

Provided is a vibration testing method for an airplane braking system. The vibration testing method for the airplane braking system is used for triggering the hidden danger of vibration failures within the service life of the braking system. The vibration testing method comprises the steps of determining the testing time according to the vibration time of the service life requirement, determining the vibration test level according to the highest vibration level within the service life period, eliminating the failures through the technology that the hidden danger of the vibration failures is triggered with a high level and displayed with a low level, mounting all products of the braking system onto an electric vibration platform in a connection mode of the system, and triggering the hidden danger of the vibration failures in the running state of the braking system. By means of the vibration testing method for the airplane braking system, the test cycle is shortened and the test cost is reduced.

Description

technical field [0001] The invention relates to the field of environmental testing of civil aircraft brake systems, in particular to a vibration test method for civil aircraft brake systems. Background technique [0002] Environmental tests are required for the development of existing civil aircraft brake system products, but the environmental tests are carried out on the products in the brake system one by one, not the entire brake system. [0003] Status abroad: [0004] The standards adopted in the environmental testing of foreign civil aircraft products include: [0005] American Standard DO-160 "Environmental Conditions and Test Procedures for Airborne Equipment", including vibration, high temperature, low temperature, temperature altitude, impact, sand and dust, and rain tests. After all the test items selected in the development contract are passed, it means the environmental test Passed; each product in the brake system is subject to the above environmental test it...
