| 中文摘要: |
| 本文以非等距Ｂ＿３样条函数为基函数分别建立了旋转壳子午向和环向形函数，其中环向形函数满足周期性条件。采取先子午向插值后环向插值的方式得到旋转壳广义样条子域位移模式。该模式可沿子午向与环向各结线任意设取结点，亦即不同环线可以有不同的结点数，从而大大提高了样条子域法的灵活性，拓宽了其应用范围。 |
| 英文摘要: |
| In this paper,the unequdistant B_3-spline function is used for establishing the meridional and circumferential shape function,and the circumferential shape function satisfies the periodic condition. The generalized spline subdomain displacement mode is got by interpolating in the longitudinal direction firstly and then in the circumferential direction. The method presented here has greatly improved the adaptability of spline subdomain method and developed its applied range,for the nodes can be set arbitrarily in the longitudinal direction and each circumferential nodal line. |
