摘要
针对传统电磁阀数学模型不能精确反映电磁阀实际换向时间的问题,提出了在电磁阀的电路、磁路、运动三个方程的基础上考虑电磁阀铁芯涡流的影响.将铁芯涡流归算为等效电阻,建立新的电磁阀动态数学模型.仿真结果表明,传统模型的开启换向时间和关闭换向时间分别为29.5 ms和30.7 ms.所建模型的开启换向时间和关闭换向时间分别为30.3 ms和35.0 ms.检测仪的实测结果为32.5 ms和35.3 ms.仿真和实测结果验证了所建模型能更准确地反映电磁阀的动态特性.
The traditional mathematical model of the solenoid valve can not accurately reflect the actual exchange time.The impact of core eddy on the basis of current,magnetism and the mechanics equations was considered.The core eddy was counted as the equivalent resistance so that a new mathematical model was established.The simulation results show that the traditional model s exchange time of open and close was 29.5 ms and 30.7 ms,while the new model s is 30.3 ms and 35.0 ms.The experimental results are 32.5 ms and...
