摘要
通过实验分析,研究磁流体的磁化性能及其流经几种特殊结构磁场时所表现出的粘磁特性.利用磁流体表观粘性随外加磁场强度变化的规律研制一种先导级无运动部件的电液伺服放大器,并给出该装置的静、动态性能实验结果.
Experimental investigations were made on the magnetization behavior of magnetic fluid and its visco-magnetic characteristics when flowing over several kinds of magnetic fields of special structures. Based on the law that the apparent viscosity of magnetic fluid changes with the intensity of magnetic field applied to,a pilot-level electro-hydraulic servo amplifier was developed without moving part. Both static and dynamic properties of the amplifier we developed are discussed.
