Embodiment 1

[0098] This embodiment is to conduct comprehensive environmental stress and operating current tests on the anti-skid brake control box of the first domestic branch line transport aircraft braking system, and propose technical improvement suggestions for the faults that occurred during the test of this embodiment. The concrete steps of this embodiment are:

[0099] Step 1. Determine the high temperature value of the comprehensive environmental stress test

[0100] When determining the high-temperature value of the comprehensive environmental stress test, first, according to the method disclosed in the invention with the application number 201310169039.1, the method of applying high-temperature stress to test the damage limit under the working state is completed to complete the test process of the high-temperature damage limit of the anti-skid brake control box, and obtain the anti-skid brake The high temperature damage limit of the control box. The high temperature value of th...

Embodiment 2

[0151] The processes of embodiment 2 and embodiment 3 all include determining the high and low temperature values ​​of the comprehensive environmental stress test, determining the temperature change rate of the comprehensive environmental stress test, determining the vibration starting point of the comprehensive environmental stress test, and determining the vibration amount of the comprehensive environmental stress test Value increase, determine the micro-vibration value and micro-vibration time of the comprehensive environmental stress test, determine the operating current applied during the test, determine the temperature holding time in the high temperature and low temperature stages of the test, and formulate the test profile of the comprehensive environmental stress. According to the test The comprehensive environmental stress test of the anti-skid brake control box is carried out on the cross-section, and each step of the test verification is carried out to the improved a...

Abstract

The invention relates to a comprehensive environment stress test method of an anti-sliding brake control box. According to comprehensive environment stress and test data, high-temperature stepping test data, low-temperature stepping test data and vibration stepping test data simultaneously exerted by working currents of the anti-sliding brake control box, a high-acceleration stress sieving test profile is made up, a method for carrying out a high-acceleration stress sieving test of the anti-sliding brake control box with three comprehensive test devices is obtained and the function of fully utilizing test data resources is achieved. With the comprehensive environment stress test method, the anti-sliding brake control box is stimulated to be sensitive to potential stoppage risks of the comprehensive environment. Simulating and correcting potential stoppage risks corresponding to the anti-sliding brake control box can be completed in two days and improvement suggestions are provided. In a testing process, an improvement technology is adopted as a development technology of anti-sliding brake control boxes of the type and the development efficiency is improved.

Description

technical field [0001] The invention relates to the field of comprehensive environmental stress test of transport aircraft electronic products, in particular to a test method for stimulating and correcting hidden troubles of an anti-skid brake control box under the joint action of comprehensive environmental stress and working current. Background technique [0002] The comprehensive environmental stress test technology for electronic products comes from the GMW8287 "Highly Accelerated Life, Highly Accelerated Stress Screening and Sampling Inspection" standard. This method is a cyclical process of imposing comprehensive environmental stress and carrying out technical improvement on the faults triggered during the test, and the improvement ends when the improvement is unconditional or the design target value has been reached. [0003] The comprehensive environmental stress in the GMW8287 standard refers to the comprehensive application of high temperature test conditions, low ...
