Armored vehicle maintainability evaluation method in virtual environment

Abstract

The invention discloses an armored vehicle maintainability evaluation method in a virtual environment and belongs to the field of maintainability evaluation. The method includes the following steps that an armored vehicle maintainability attribute set is preset; according to the subjective weight assignment of experts and the cloud theory, an armored vehicle maintainability evaluation sub-attribute weight cloud is determined; an armored vehicle maintainability evaluation sub-attribute index cloud is determined; an armored vehicle maintainability evaluation comment cloud is determined through the golden section method; each attribute cloud parameter is compared with the comment cloud in similarity, and according to the maximum membership degree principle, evaluation comments of each attribute are determined; according to comments of each sub-attribute of the armored vehicle maintainability, the armored vehicle maintainability in the virtual environment is evaluated, moreover, according to armored vehicle maintainability feedback opinions given by the experts in the evaluation process, the armored vehicle maintainability engineering application is guided, and the armored vehicle maintenance level is improved. The method can reduce the subjectivity of the armored vehicle maintainability evaluation, the objectivity of the evaluation method is improved, and the systematicness and integrity of the evaluation process are improved.

Description

technical field [0001] The invention relates to an armored vehicle maintainability evaluation method in a virtual environment, belonging to the field of maintainability evaluation. Background technique [0002] For some large-scale mechanical products, the finalization of the design means the determination of the maintenance performance. Once such products do not have good maintainability, it will often cause difficulties in later maintenance and bring huge use costs. Armored vehicles are special large-scale mechanical products. If maintainability factors are not fully considered during the design process, once the design is finalized and the product is put into production, future maintenance will consume huge manpower and financial resources. The country causes unnecessary losses, and even affects the combat efficiency in wartime, which is directly related to our interests and national defense security. [0003] Traditional armored vehicle maintainability design analysis a...
