一种新型直动式电液伺服阀的研制

Research on a New Direct Driven Electro-hydraulic Servo Valve

基于一种永磁极化式双向比例电磁铁和耐高压电涡流位移传感器,提出一种新型直动式电液伺服阀,进行性能仿真分析,设计出相应的驱动电路并进行实验研究。实验结果与仿真结果吻合,表明提出的电液伺服阀具有良好的静态特性。

Based on a permanent-magnet polarized bidirectional proportional solenoid and a high-pressure eddy current displacement sensor, a new direct driven electro-hydranlic servo valve was presented. Simulation analysis was given. The driving circuits for the valve were designed and experimental research was carried out. The experimental result agrees well with the simulated result. It shows that the servo valve has good static characteristic.
