| Abstract: | The jam fault of the electro-hydraulic servovalve is analyzed by means of simulation. The amplitude and frequency of the electro-hydraulic servovalve's vibration has influence on the jam,and which is analyzed in the paper. A method to diagnose the fault is given based on analyzing the vibration amplitude. |
