摘　　要：采用有限元法对交流发电机在突然短路时定子绕组端部及绑扎带应力进行计算.通过对电机绕组的三维场物理模型划分为8000多个三维实体单元、11000多个节点,并结合工程实例求出其各部位受力情况,找到最大应力点,从而为定量解决这一设计难题求得一种精确计算方法.Using finite element method to calculate the stress of stator coil head and colligation band of the alternator which suddenly occurs short circuit. Through dividing the coil and band into more than 8 000 three_dimensional elements and 11000 nodes, in association with the engineering example, the stresses of each region and the maximum stress point are calculated. Thereby a sort of refined calculation approach to solve this design puzzle is acquired.
