摘要
为了满足舰面维修人员对海军航空装备维修保障的需求,提出了航空装备故障损伤等级的可拓评定方法;首先,给出了故障元的概念,以形式化描述航空装备发生的故障及故障的判别特征;其次,给出精准度的概念,对判定故障判别特征量值的准确性进行刻画;在此基础上,利用可拓学的可拓识别方法对航空装备发生故障的损伤等级进行综合评定,提供一种确定航空装备故障损失等级行之有效的途径和方法,为确定故障维修计划及方案提供重要的理论参考借鉴;最后,通过某次远航中直升机发动机的故障算例分析显示:该方法可靠、简单、实用,具有较好的推广应用价值。
in order to meet the requirements of naval aircraft maintenance support for naval aircraft maintenance personnel,an extension evaluation method for fault damage level of aeronautical equipment is proposed.The concept of fault element is given,and the fault of aeronautical equipment is described formally.The concept of accuracy is introduced to characterize the accuracy of discriminating characteristic values.Based on that,the damage degree of aeronautical equipment failure is evaluated by extension theory and method,which provides important references for identifying fault maintenance programs.The calculation example shows that the method is reliable and practical,and has good application value.
