Problems solved by technology

[0003] At present, there are many softwares for FMECA analysis of products at home and abroad, but due to the complexity and particularity of aviation airborne mechanical products, there is no special method for FMECA analysis of airborne mechanical products.
The current problems in the FMECA of aviation airborne machinery products are: (1) The combination of FMECA and product design is not enough; (2) The failure modes of parts are not considered comprehensively; (3) The relationship between parts, finished products and systems It is difficult to sort out the transitive relationship between failure modes

Abstract

The invention relates to an FMECA analysis method of aviation onboard mechanical products. The FMECA analysis method of the aviation onboard mechanical products comprises the steps that step a, a typical part failure mode database is built; step b, an FMECA database is built; step c, preparation work before FMECA analysis is carried out; sep d, the design and input of FMECA information of a single part are finished; step e, the FMECA information is stored, the next part is designed, the FMECA information is input and stored until the design of a whole product is finished; step f, FMECA analysis is carried out on the product; step g, an FMECA analysis report is output. The FMECA analysis method of the aviation onboard mechanical products can achieve tight combination of product design and FMECA analysis of the product, systemically manage the FMECA information of each part and clearly reflect the hierarchical relation of the parts of the product.

Description

technical field [0001] The invention relates to the field of aircraft design, in particular to an FMECA analysis method for aviation airborne mechanical products. Background technique [0002] Failure Mode Effects Analysis is an analysis method used to determine potential failure modes and their causes. Failure Mode and Effects Analysis (FMEA) and Criticality Analysis (CA) are collectively referred to as FMECA. It is summed up in engineering practice, based on the failure mode, and the analysis technology aimed at the failure effect or consequence. It comprehensively identifies weak links and key items in the design by analyzing the impact of different failures of each component on the system work one by one, and provides basic information for evaluating and improving the reliability of the system design. At present, in many important engineering fields, FMEA has been highly valued by research managers, and is clearly stipulated as a technology that design researchers must ...
