扁薄锥壳非对称大变形问题

Non-Symmetrical Large Deformation of a Shallow Thin Conical Shell

摘要: 本文用双参数摄动法研究了扁锥壳非对称大变形问题,求得了在线性载荷作用下的扁锥壳变形的三次近似解析解并绘出了摄动点的挠度与载荷的特征曲线。应用本文方法还可对其它板壳的非轴对称大变形问题进行讨论。本文通过算例对平板及不同初挠度的扁锥壳大挠度变形进行了讨论。

Abstract: In this peper, non-symmetrical large deformation problem of a shallow conical shell is studied by two-parameter perturbation method. The third-order approximate analytical solution of the deformation of a shallow conical shell subjected to linear loads is abtained and the characteristic curves of loaddeflection on a perturbin point are portrayed. The similar questions of other kind of shell and plate can be disscussed by using this paper's method. As the examples, the large deflection of plate and shallow conical shells with different initial deflections is discussed.
