| 摘 要： | 根据发动机泵机组中各部件在不同故障下的特征频率,利用小波变换多分辨率特性,提取出发动机泵机组的各类故障特征信号,经分析后找出故障原因。在确定故障原因的基础上,利用支持向量机原理在解决小样本、非线性、高维模式识别问题的优势,建立支持向量机故障诊断模型,对某发动机泵机组进行了故障诊断,得到了很好的效果。 |

| Abstract: | Deliver motive pump machine has different fault character in each parts of set frequency.Using the character of wavelet transformation with many resolutions and withdrawing each kind of fault characteristic signal of Deliver motive pump machine,it is able to find out the fault by analyzing.Further more,by making use of the advantage of support vector machine in solving small samples,non-linearity and higher-dimension pattern recognition problem,the authors carried on fault diagnose to one Deliver motive pump machine by the establishment of fault diagnosis model with support vector machine and got good result. |
| Keywords: | Wavelet transformation Deliver motive pump machine Fault diagnosis Support vector machine(SVM) |
