摘要：利用数值模拟分析软件ANSYS，模拟分析平面交流感应电磁泵对泵沟内流通的液态金属作用的电磁驱动力变化。通过模拟结果得知，在相同加载条件下，液态Na-K合金液、Ga液、Zn液及Sn液由于电阻率值不同，所受电磁泵电磁驱动力依次减小；改变电磁泵窄面泵沟材料分别为不锈钢板、铜板、银板及陶瓷板时，可知窄面泵沟材料为铜板或银板时液态金属Zn受到的电磁驱动力较大且两者值相近，同时增加铜板厚度也有利于电磁驱动力的提高；在三相交流电源供电条件下，电磁泵加载不同电流频率，液态金属Zn受力呈现随频率增大先升后降的趋势，得到最佳使用频率范围为40～60Hz。

Abstract:The variation of the electromagnetic driving force generated by flat alternating current induction electromagnetic pump when the liquid metal flowed into the pump ditch was simulated and analyzed by using the numerical simulation analysis software ANSYS.Based on the simulation results,it can be concluded that the electromagnetic driving force endured by the liquid potassium-sodium alloy,liquid gallium, liquid zinc and liquid tin respectively are decreased in turn because of the difference of the resistivity to a definite liquid metal on the same loading condition. After changing the material applied on the narrow side pump ditch to stainless steel plate,copper plate,silver plate or ceramic plate separately,it is not difficult to find out that the electromagnetic driving force is larger under the circumstance of using a copper plate or a silver plate, and the values of the electromagnetic driving force in those cases are approximate. Meanwhile,increasing the thickness of the copper plate is also beneficial to the improvement of the electromagnetic driving force. The electromagnetic driving force on the three-phase alternating-current supply is fluctuated ,presenting a trend of increasing at the beginning and then decreasing with the gradual increase of the loading frequency .The optimal applicable range of the loading frequency is from 40 to 60 Hz.
