中文摘要：

直线感应电机可以将电能直接转换成直线运动的机械能。它具有广阔的应用和发展前景。论文对比较常用的低速扁平单边型直线感应电机展开分析，基于ANsOFT二维瞬态场改变电机的次级导电部分结构对初级受电磁力进行计算，定性作出这些参数对电机电磁力影响的结论。仿真结果表明，次级导电部分厚度对初级受推力影响明显，距初级距离对初级受推力影响很小。当次级导电部分被与初级等宽、两端导通的铜条取代时，单根铜条面积越大，两根铜条间隙越小，产生推力越大而平稳。该结论为后续研究打下坚实基础。

英文摘要：

Linear induction motor can convert electrical energy into the linear motion of the mechanical energy directly. It has broad ap plication and development prospects. This paper analyzes the commonly used low-speed flat the single-sided linear induction motor. Based on Ansoft 2D transient field, calculate the electromagnetic force when change the motor secondary conductive part of the structure of the prima ry, and then we drew qualitative conclusions, how the electromagnetic force is influenced by these phrameters on the motor. Simulation re suits show that, the tluckness of the secondary conductive portion significantly could affect the thrust of the primary subject in effect, little effect on the primary subject thrust away from the primary distance. When the secondary conductive part is replace by the copper strips whose width is equally to the primary, and both ends of copper strips is conduction, the larger the single area of the copper bars, the smaller the gap between two copper bars, the greater and the smoother the thrust. The further study could be based on this conclusion.
