摘要:
为了提高电液高速开关阀的开关速度 ,改进流体脉宽调制 (PulseWidthModulation ,简称PWM )电液数字控制的精度 ,对以稀土合金超磁致伸缩材料作为驱动器来驱动液压开关阀进行了研究 ,并研制了一种特殊结构的新型高速开关阀。仿真计算与试验结果表明 ,这种阀具有很高的切换速度及频率 ,其开关时间少于1ms,能够显著地提高PWM电液控制精度。
Abstract:
In order to improve the sw itching speed of an electro-hydraulic high-speed on-off v alve and the digital cont rol accuracy of the f luid pulse w idth modulation ( PWM) , this paper made some researches about using the rare-earth-alloy g iant magnetost rict ive as an actuator to drive the hy draulic on-off valve, and a kind of new high-speed on-off valve w ith a special st ructure w as made. T he results of simulat ion calculat ion and ex periment showed that the valve had very high sw itch speed and f requency, and it s on-of f t ime w as less than 1ms. T he cont rol accuracy of elect ro-hydraulic PWM can be much raised by using the high-speed on-off valve.
