摘要
详细分析了独立于LRU的PHM方法和基于故障征兆预测的PHM方法的预测原理。利用LRU和PHM的MTBF概率分布和socket的全寿命周期费用建立仿真模型,介绍模型仿真方法与详细过程。研究了末段高层反导武器系统单socket全寿命周期费用与安全极限和预测距离的关系。引入同步时间的概念,利用单socket模型的方法优化多socket组成的系统。模型仿真结果更贴近末段高层反导装备实际,比单socket模型更有应用价值。
The forecast theories of LRU-independent methods and precursor to failure monitoring are analyzed in detail. A multiple socket model is built by utilizing the probability density function of MTBF and LCC of socket for modeling, and the simulating method and its particular process are introduced. Then, the relations between single socket LCC of terminal high altitude antiballistic missile weapon system and safety margin or prognostic distance are studied. The conception of coincident time is introduced, and then the single socket model is used to optimize system which is composed of multiple sockets. Simulation results presses close to terminal high altitude antiballistic missile equipment and is much more valuable than single socket model.
