登船栈桥圆筒体的屈曲分析

Buckling Analysis on Cylinder in Trestle

运用理论法和有限元数值法,分析了登船栈桥设计中的圆筒体屈曲,对比了理论、特征值和非线性屈曲分析的临界载荷,得出了圆筒体屈曲的分析结论;分析了加筋对圆筒体屈曲的影响,给出了圆筒体加筋设计的合理建议。

The theoretical method and finite element numerical method are applied to research on the buckling of cylinder. The conclusions of the buckling of cylinder are put forward by contrasting theory,eigenvalue and critical load from nonlinear bucking analysis. In addition,the influence of stiffeners is analyzed and reasonable reference is carried out.
