Behavior of Electro-Hydraulic Servovalve in Accelerated Field

概要

論文の詳細を見る
The dynamical behavior of an electro-hydraulic servovalve regarded as a combined electro-mechano-hydraulic system, which is especially subjected to external vibratory disturbance, is analysed. The theoretical results of frequency response concerned with the port opening versus input electric signal and also external vibratory displacement are found to agree well with the actual test results under standstill condition and also under external vibration. It is pointed out that the servovalve under test has a very good frequency response up to 500 Hz even in a vibrating accelerated field, provided that the magneto-mechano-hydraulic damping of the torque-motor in it is properly selected.
