作战飞机可靠性与维修性仿真模型

通过故障树分析建立了作战飞机仿真逻辑关系。在修正线性同余法的基础上获得了随机数模型。在各设备故障发生状态和修复状态识别的基础上,建立了可靠性维修性仿真模型,确定了作战飞机在仿真过程中的工作状态,并根据故障模式影响分析预计了设备故障对作战飞机的影响。最后以F/A-18为例进行可靠性维修性仿真,获得了实时的故障信息和修复信息,验证了仿真模型的可行性。

Reliability and Maintainability (R&M) Simulation Model of Combat Aircraft

Simulation logic relation of combat aircraft is established through fault tree analysis in this paper,and the random number model is obtained though revising the method of linear congruence,and by identifying the failure state and repair state of equipments,the reliability and maintainability(R&M) simulation model is established,and the aircraft working state is determined,the failure effect on the aircraft is also estimated with failure mode and effect analysis (FMECA).Finally,we verified the simulation model with the example of F/A-18,and the failure and repair information of actual time is acquired,as a result it is feasible in practice.
