摘要
本文将样条有限点法应用于变厚度圆柱壳的动力分析。推导出了适用于各种边界条件的统一格式,便于在计算机上实现。与通常的有限元法相比,具有计算量少、精度高等显著的优点。文中各种计算结果得到了现有文献成果的验证。
In this paper the spline finite-point methodis applied to the dynamic analysis of cylindrical shell with variable thickness. A computational scheme well suited for various types of boundary conditions is derived and can be easily carried out by a computer. In comparison with the usual nodal finite element method, the main features of the present method are higher accuracy and more economyin computing storage and time. All the calculating results obtained from this study are verified by those from current literatures.
