    摘要:

    為了能夠準確地進(jìn)行裝甲車(chē)輛電源系統的故障診斷,深入地研究了故障樹(shù)分析法在其中的應用;首先,以某型裝甲車(chē)輛電源系統為研究對象,根據系統失效模型和故障機理,將故障樹(shù)分析法運用于裝甲車(chē)輛電源系統故障診斷中,建立電源系統故障樹(shù)模型,進(jìn)行故障分析與診斷;其次利用電源系統故障診斷平臺對電源系統4個(gè)模塊進(jìn)行故障模擬仿真研究,可看出故障樹(shù)分析法能夠準確地診斷出電源系統各個(gè)模塊的故障,檢測精度可達94%,取得了預期效果。

    Abstract:

    In order to carry out fault diagnosis of armored vehicle power system correctly, the application of fault tree analysis is studied in depth. Firstly, select a certain type of armored vehicle power system as the research object. According to failure modes and failure mechanism of the armored vehicle power system, FTA is used to armored vehicle power system fault diagnosis. The fault tree is built up and failure analysis exclusion is carried out. And then the simulation of fault diagnosis of four modules of the power system is carried out by the power system fault diagnosis platform. The results show that fault tree analysis can obtain the fault of power system correctly, and the detection accuracy as high as 94%. Anticipative results have been achieved when it was used to armored vehicle power system.
