摘　　要：根据提供的图纸,经过适当简化,在有限元分析软件ANSYS内建立了直线电机定子的三维实体模型,进行了初步静态分析,得知定子平面内的力与垂直于定子平面的力相比可以忽略不记。根据动子的运动规律对定子实施了分步加载,得到有限元完全瞬态分析结果。由结果知,动子对定子作用的动态部分相对于静态可以忽略,分析结果与现场十分吻合。According to the drawing offered, after proper simplification, the linear electromotor stator＇s 3 D entity model is designed by use of ANSYS, finite analysis software. After the initial static analysis, we know that the force in the plan of the stator can be neglected compared to the one upright to the stator. According to the motive mechanics of the actor, the force is loaded step by step on the stator. Finally, we got the finite element full transient analysis result, and the result is quite agreeable with the practice. From the analysis result we know that the dynamic can be neglected compared to the static.
