摘要
本文用壳条加筋元和流体边界元统一分析了用纵筋加强的环肋柱壳静动力性能。利用 D′Alembert 原理和 Hamilton 变分原理建立系统运动控制方程。对纵筋和环肋的布置形式、尺寸大小和根数变化对其静动力性能的影响进行了系列讨论,得出一些有实用价值的结论。
A numerical method for buckling and dynamic analysis of ring-stiffe- ned cylindrical shells with longitudinal stiffeners is presented.Control equ- ations of motion of the system is derived by using D'Alember principle and Hamlton varition principle.The effect of the arrangement of the longitudi- nal stiffeners and the circular transverse frames,the variation of its size and numbers on the static and dynamic performance characteristics are di- scussed.Some conclusions with practical use are derived.
