摘　　要：针对某型号矿用电磁铁启动电磁力低、不足以驱动控制阀的问题,在控制电压、电磁铁外形尺寸和阀芯行程不变的前提下,应用有限元仿真软件Ansys-Maxwell分别对电磁铁中隔磁环长度和隔磁环位置对启动电磁力的影响进行参数化仿真分析。仿真结果表明:隔磁环长度对启动电磁力影响不大,隔磁环位置对启动电磁力有重要影响。研究得到的最终优化方案是当隔磁环位置左移3.0 mm后,矿用电磁铁的启动电磁力由3.47 N增加到13.9 N,远大于控制阀的开启液压力4.12 N。通过试验验证了仿真分析的正确性。With regard to the deficiency of driving the control valve of a certain type of mining electromagnet due to its low starting electromagnetic force,and on the premise that the control voltage,the outline dimension of the electromagnet and the stroke of the valve core remain unchanged,the finite element simulation software Ansys-Maxwell is used to carry out parametric simulation analysis on the influence of the length and position of the magnetic separator ring in the electromagnet on the starting electromagnetic force.The simulation results show that the length of the magnetic separator has little effect on the starting electromagnetic force,the position of the magnetic separator,however,has an important effect on the starting electromagnetic force.The final optimization scheme obtained from the research is that when the position of the magnetic separator ring is moved to the left by 3.0 mm,the starting electromagnetic force of the mining electromagnet increases from 3.47 N to 13.9 N,which is far greater than the opening hydraulic pressure of the control valve of 4.12 N.The vadility of the simulation analysis is verified by experiments.
