摘要/Abstract

摘要：

由于军机使用环境的特殊性，其维修大纲制定与民机所考虑的因素有所不同。以民机金属结构环境损伤模型为基础，通过对军机维修标准的研究，分析了影响军机金属结构环境损伤的主要因素，建立了军机金属结构环境损伤模型。提出利用G1 法确定模型中各指标权重及引入专家权重对其进行修正的指标评价方法。考虑到服役环境对指标评定的影响，对飞机某部件在3 种服役环境下的损伤等级值进行了实例分析，并利用G1-灰色关联系数方法进行了验证。

Abstract:

The maintenance program compiling of military aircrafts is different from civil aircrafts because of the special working environment of them. On the basis of civil aircraft metal structure environmental damage modeling, the relevant standards for military aircraft are studied. The main factors about the environmental damage of military aircraft metal structure are analyzed thoroughly and the military aircraft metal structural damage assessment model is created. G1 method is used to determine the weight of each index which is modified by the expert weight. By using the above methods, the damage level of a certain part under three kinds of services environments is obtained by taking into account the military aircraft service. Finally, the model which is called G1-Grey relational coefficient is used to verify the method.

Key words: military aircraft, environmental damage, G1 method, Grey relation
