| 摘 要： | 由圆柱壳的运动方程推导出圆柱双壳系统的耦合方程，并将其应用于大型发电机定子系统的响应分析。本是半解析法，其特点是将圆柱壳的三维弹性运动方程表达成Hamilton正则方程，没有应力和位移模式的假设，不限制壳的厚度；同时，象一般有限元方法一样该方法适应复杂的边界条件，未知量少于一般有限元方法，计算速度快，数据准确方便，适合工程应用。

| Abstract: | The coupling equation of cylindrical double - shell system is derived from the circular cylindrical equation of motion, and it is employed to analyze the response of large turbogenerator stator system. Characteristics in the method are the assumption of stress and displacement is given up and also the wall thickness of cylindrical shell is not restricted, Meanwhile, the method is similar to the general finite element method (FEM) meets complex boundary conditions, but unknown is less than that of general FEM, the speed of analysis is quick, the data of preparation is convenience, it is suitable for engineering. |
