| 摘 要： | 从电液转换器结构着手建立数学模型并转换成传递函数模型,在Matlab中对其典型故障的动态特性进行仿真研究．研究结果表明电液转换器的不同故障具有明显不同的动态响应,因此可以通过电液转换器的响应特征识别不同的故障,这对通过试验的方法识别电液转换器故障具有一定的指导意义,为利用对象的响应特性识别故障打下基础．

| Abstract: | Mathematical models were built through the structure of electronic hydraulic convertor and converted into transfer functions. These functions were studied in Matlab to simulate the dynamic performance of electronic hydraulic convertor under malfunction. The results showed different failures had different dynamic responses. And different malfunctions can be identified by different dynamic responses. This conclusion is of great importance for malfunction identification through test and for further research. |
