摘要
介绍了自动变速器用比例电磁阀电磁力的2种计算方法即经验公式法和模拟计算法,通过Flux软件模拟分析电磁阀的电流、电磁阀行程和电磁力之间的关系,以及隔磁环的位置对电磁力的影响,并通过对隔磁环位置为4.5 mm的电磁阀试验,得到的电磁力验证了模拟计算的结果。
The calculation method,experimental formula simulation method,for electromagnetic force in AMT proportional solenoid valve was elaborated.The relationship among electromagnetic force,current and stroke was described,and the influence of diamagnetism-ring’s position on electromagnetic force was analyzed with FLUX.According to the experimental results of solenoid valve in which diamagnetism-ring located in 4.5mm,electromagnetic force was identical with simulation results.
