| 摘 要： | 如何计算大型纵向加筋截断锥壳的稳定问题，尚未见到有关报导。本文在沿纵向和环向分别采用Ｈｅｒｍｉｔｅ插值和三角级数插值的基础上，建立了几何非线性带筋环单元，进而导出了半离散分析法，并经过实例检验了它的正确与可靠。这样，本文为建立各类工程结构的半离散单元提出了一种新的途径。

| Abstract: | How do calculation stability problems problems for large conical stiffened with longitudialribs,cannot yet issue in repord. In this paper,by applying the Hermite and trigonometricseries interpolation along the longitudinal and circumferential direction respectively,a newkind of geometrically nonlinear ring elements stiffened with ribs has been developed.The se-mi-discrete analysis method for the stability of large conical shell stiffenet with longitudinalribs is propose. The correctness and effectiveness of the analgsis is verified by examples.Thus,a kind new theory and method for establishment variaus kind semi-analytical elementsof engineering structure is proposed. |
