Abstract:
The magnetic
fluid is used as working medium in pilot stage of
electro-hydraulic servo amplifier. Utilizing the magnetization
viscous character of the fluid, a new type of electro-hydraulic
servo amplifier without any moving parts in its pilot stage has
been developed. This research provides a way for improving the
frequency property and reliability of electro-hydraulic servo
elements.
