摘　　要：为了比较分析变压器低压绕组在短路电动力作用下的径向屈曲临界压力,采用多弹性端点支承的模型模拟了初始几何缺陷下径向屈曲临界压力的变化情况,根据有限元分析建立了两端支承的模型。According to Finite element method,Models are establised by supported from both ends and multiple elastic ends.To comparative analysis critical pressure of radial buckling when the LV inner winding of a transformer subjected to radical electromagnetic forces under short circuit conditions.And the model which supported by multiple elastic ends simulates the change of critical pressure of radial buckling in initial geometric imperfection.
