摘要: 高速开关阀是数字液压系统的关键控制元件,需要快速响应启闭信号以实现数字液压系统的精准控制。然而,高速开关阀的启闭过程存在不可避免的电磁滞后,延长阀的启闭响应时间。为此,通过多物理场耦合分析及电流-电磁力检测试验,发现驱动电流与输出电磁力之间存在不可忽略且不同于常规B-H磁滞特性的滞后关系,揭示电流-电磁力之间的滞后规律。研究结果表明,磁滞和涡流会阻碍高速开关阀电-机械转换器的充磁和退磁,使得动态开启电流大于静态开启电流,动态关闭电流小于静态关闭电流。而且激励电压越大,动态启闭电流与静态启闭电流之间的差异越大,启闭响应时间越短;启闭初始磁通所产生的电磁力越接近临界启闭电磁力,可在减小动态启闭电流与静态启闭电流之间差异的同时,缩短启闭响应时间。基于此规律,在24 V开启电压和-24 V关闭电压激励下,通过调控开启和关闭阶段的初始电流使其临近静态临界开启电流值1.04 A和静态临界关闭电流值0.52 A,可使开启阶段内的动态开启电流从2.92 A降至2.70 A,并避免在电磁力下降至临界关闭电磁力前出现再充磁现象。基于以上结论所制定的控制策略,经样阀测试后,开启响应时间可达到0.28 ms;关闭响应时间可达到0.32 ms。

Abstract: High speed on/off valve(HSV) is a critical component in digital hydraulic system, requiring rapid response to switching signals for precise control of digital hydraulic system. However, its opening and closing process is inevitably affected by electromagnetic hysteresis, which prolongs the HSV’s response time. Through multi-physics coupling analysis and current-electromagnetic force experiments, a significant hysteresis relationship between driving current and output electromagnetic force, distinct from conventional B-H hysteresis, is found, and the hysteresis law between current-electromagnetic force is obtained. Results show that magnetic hysteresis and eddy currents hinder the magnetization and demagnetization processes of the electro-mechanical converter, causing the dynamic opening current to exceed the static opening current, and the dynamic closing current to fall below the static closing current. Additionally, larger excitation voltages result in greater differences between dynamic and static opening/closing currents but shorter response times. Furthermore, when the electromagnetic force generated by the initial flux of opening and closing gets closer to the critical opening and closing electromagnetic force, the difference between dynamic and static opening/closing currents is reduced, and the opening/closing response time is shortened. Under 24 V opening and -24 V closing voltages, regulating the initial current close to the static critical opening/closing current value of 1.04 A and 0.52 A, reduces the dynamic opening current from 2.92 A to 2.70 A, and prevents re-magnetization before the electromagnetic force decreases to the critical closing value. Based on the above conclusions, the developed control strategy can achieve a opening response time of 0.28 ms; and a closing response time of 0.32 ms after being tested on a sample valve.
