摘要
为解决军机线路短路和断路失效的问题,对基于比例危险模型的军机线路失效进行分析。通过对可能导致线路失效原因的分析,建立军机线路失效模型,对比例危险模型参数进行估计,采用SPSS软件进行生存分析,计算线路的失效率,推算出电线的大致失效时间。分析结果表明:该模型提高飞机电气线路的安全性和可靠性,可为军机电气线路的风险评估提供参考依据。
To resolve the short circuit and broken circuit failure of military aircraft wiring,wiring failure based on proportional hazard model is analyzed for the military aircraft.By analyzing the reason of wiring failure,the model of wiring failure is built for military aircraft and the parameters are estimated for the proportional hazard model.Survival analysis is carried out based on of the SPSS software to compute the failure probability and to calculate the failure time of wirings.The analyzed results show that this model improves the safety and reliability of electrical wirings for aircraft and can provide the research references for the risk assessment of electrical wirings for military aircraft.
