摘要：

针对电磁开关阀内部阀芯运动过程难以被精准检测的问题，提出基于电流多阶导数特性的电磁开关阀动态性能无损识别方法. 考虑电磁铁线圈温升对线圈电阻的影响规律，以线圈电感导数、电流导数和阀芯运动速度建立数学模型. 基于磁化曲线探究电流导数与阀芯运动状态的匹配关系，分析磁导率导数对判断电磁开关阀启闭状态的影响规律. 推导得到开启电流导数中的凸/凹点对应电磁开关阀的临界/完全开启时刻，关闭电流导数中的上/下折点匹配电磁开关阀的临界/完全关闭时刻. 试验结果表明，开启和关闭时间最大检测偏差分别为2.40%和3.08%，单周期总启闭时间最大检测偏差为1.49%.

Abstract:

A non-destructive identification method for the dynamic performance of the solenoid switching valve (SSV) based on multi-order current derivative characteristics was proposed, aiming at the problem that the moving process of the valve spool inside the SSV was difficult to detect accurately. Considering the effect of the solenoid’s temperature rising on the coil resistance, a mathematical model among the coil inductance derivative, current derivative and spool moving velocity was established. The matching relationship between the current derivative and spool moving state was explored based on the experimental magnetization curve, and the influence of the permeability derivative on the judgment for each switching state of the SSV was analyzed. Theoretical analysis deduced that the convex point and concave point on the opening current derivative curves corresponded to the critical opening moment and fully opened moment of the SSV, and the upper and lower turning points on the closing current derivative curves matched the critical closing moment and fully closed moment of the SSV. Experimental results showed that the maximum measurement deviations of opening time and closing time were 2.40% and 3.08%, respectively, and the maximum measurement deviation of total switching time in a single cycle was 1.49%.
Key words: solenoid switching valve    temperature rising characteristic    dynamic performance    high accuracy detection    current derivative
