基于证据理论的多技术油液分析信息融合故障诊断

Fault Diagnosis on Multi-technique Oil Analysis Information Fusion Based on D-S Theory

将证据理论应用于多技术油液分析故障诊断的研究中,针对证据理论的核心——基本概率分配函数的构造问题,提出了新的构造基本概率分配函数的方法,并将该方法应用到某综合传动机构的可靠性试验中,试验结果表明,该方法能很好地识别出故障模式,具有较好的应用价值。

Through applying the D--S theory on the fault diagnosis research by the multi--technique oil analysis information fusion, the new methods for constructing the basic probability assignment was created to settle the key problem of the D--S theory. The fault symptom of the power-- shift steering transimission（PSST） can be captured by using this method on the oil analysis of the reliability test, and this method can be used for engineering applications.
