摘　　要：用伽辽金有限元法计算了往复运动的圆筒型直线感应电动机的动态温度场。在计算中 ,考虑了材料的电阻率及导热系数在动态过程中的变化。计算结果与试验结果吻合较好。In the paper,the dynamic thermal field of cylindrical linear induction motor running in oscillating motion is computed by using Galerkin FEM.In computation,the change of electric resistivity and thermal conductivity of materials during the dynamic process is taken into account.Calculated values are in good agreement with experimental results.
