| 摘 要： | 本文从柴油机燃油压力波的特征出发,建立ARI(Auto—Regressive Integra—ted)时序参数模型.通过对不同故障下的燃油压力波基于ARI时序参数的现代谱分析,说明ARI时序参数模型较好地揭示了燃油压力波蕴含的故障信息.通过燃油压力波的ARI时序参数构造故障诊断模式向量,根据几何距离与信息距离的测度来诊断故障,具有一定的实践意义.

| Abstract: | This paper mainly studies how to form the ARI (Auto - Regressive Integrated) time series models of the OPW,and analyses the modern spectrum based on the model parameters for the faults,in the meantime,applies the pattern recognition to study the simulated faults by some of the distances. |
