| 摘 要： | 由于水压试验机机理建模的复杂性,很难从机理方面对其生产过程进行故障诊断,因此利用钢管水压试验系统过程变量多、打压速度快,短时间内能够产生大批数据信息的特点,提出了基于多时段多向Fisher判别分析方法用于水压试验机打压过程的故障诊断.该方法根据不同的故障在不同的时段有不同的表征,将水压机生产过程分成多个时段,对每个子时段的数据分别建立MFDA模型用于故障诊断.采用了水压试验机生产过程的几类故障数据对该方法进行验证,结果表明该方法具有很好的故障诊断性能. |
| 关 键 词： | 故障诊断 水压试验机 多向Fisher判别分析 多时段 |

| Abstract: | Hydraulic tube tester is a complex system composed of mechanics,hydraulics and electronic control et al.,in which the diagnosis and exclusion of faults bear great technique difficulty.On the other hand,fault diagnosis based on MFDA(multiway Fisher discriminant analysis) has high diagnostic capability because it takes advantage of both normal and fault data in modeling.Therefore, a multi-stage multiway fisher discriminant analysis method on Hydrostatic tube tester is introduced for fault diagnosis.The method... |
