摘要
为解决风险随机性大、多因素交互的飞机主起落架系统（AMLGS）故障问题,构建图示评审技术-蒙特卡罗（GERT-MC）故障风险传递模型;利用GERT网络中并联结构、自环结构和环路的简化规则,以及蒙特卡罗方法,设计仿真求解算法;以某飞机主起落架为例,用上述算法计算其总体风险度、确定关键风险环节,并与解析法计算结果对比。研究表明：该模型具有与解析法同样的解算精度,且具有更好的可信性,利于加强飞机维修监控的针对性。
A model of failure risk transmission based on GERT-MC was built to solve the problems of randomness and interaction between failure risks in AMLGS. The series and parallel and loop structures of GERT were simplified,and the MC simulation method was used to design a simulation solving algorithm for the model. System risk and key links of failure risk were identified exactly for an AMLGS taken as an example. A comparison between the analytical and simulation methods showed that the model is effective in quantitative analysis and control of transmission of failure risks in an AMLGS.
