Embodiment Construction

[0020] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0021] An aircraft airborne equipment testability verification index evaluation method, the specific steps are as follows:

[0022] 1) According to the FMEA report of the product, determine the failure mode set F of the product;

[0023] 2) Analyze all the failure modes in the failure mode set F of the product, and determine the failure mode sets that can be physically injected in the laboratory and the failure mode sets that cannot be physically injected;

[0024] 3) According to the failure mode determined in step 2) is all the failure mode sets that can be physically injected, then formulate the test plan, carry out the testability verification test, and complete the testability evaluation;

[0025] 4) According to the failure modes determined...

Abstract

A testability verification index evaluation method for airborne equipment of an aircraft is provided. The method comprises the steps of: first, according to the FMEA report of the product, determiningthe failure mode set F of the product, and then analyzing all the failure modes in the failure mode set F of the product to determine a failure mode set that can be physically injected and a failuremode set that cannot be physically injected by the laboratory,; when determining that the failure mode is the failure mode set that can be physically injected completely, making a test scheme, carrying out the testability verification test, and completing the testability evaluation; if the determined failure mode has a failure mode that cannot be physically injected, splitting the product failuremode set F, and redetermining the failure mode set of the split product, and carrying out the corresponding analysis and evaluation. By synthetically weighting testability verification and fusing multi-faceted information, the integrity and adequacy of experimental data sources can be ensured and the accuracy of testability evaluation can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of aircraft test analysis, in particular to an evaluation method for testability verification indicators of aircraft airborne equipment. Background technique [0002] At present, the testability verification and evaluation methods of aircraft airborne equipment are mainly statistical methods, including testability evaluation methods based on binomial distribution and normal distribution. The standards that can be referred to mainly include GJB2072, GJB1770, GJB5080, GB4087, etc. However, the current aircraft airborne equipment testability verification test cannot inject all failure modes of the product, resulting in insufficient sample space in the test. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a testability verification index evaluation method for aircraft airborne equipment to solve the above-mentioned shortcomings in the background tech...
