摘要：
In order to reduce the subjectivity of identifying the key design quality characteristics of products and ensure the scientific sequencing, a method of identifying and sequencing key design quality characteristics of products by reverse reasoning from the perspective of fault feedback was proposed. Firstly, in order to reduce the fuzziness and redundancy of information in fault analysis, product element faults were extracted based on extension operation. Taking the meta-fault, the fault cause and the key design quality characteristics as the basic correlation elements in the reverse reasoning processes, the extended correlation model of key design quality characteristics was established by analyzing the vertical correlation between different levels of "meta fault-failure cause-key design quality characteristics" and the horizontal correlation between same level. Based on this model, a quantitative expression model and algorithm for the influence breadth and influence depth of key design quality characteristics were established, and a quantitative ranking of key design quality characteristics was realized through directed graph and failure mode and impact analysis. Finally, the effectiveness of the proposed method was verified by a case of crane hoisting mechanism. © 2022, China Mechanical Engineering Magazine Office. All right reserved.
