| 摘 要： | 研究了在横向均布载荷和温度载荷作用下的一类薄环板与扁薄锥壳组合结构的大变形问题.利用打靶法对周边固定和周边简支的问题进行了数值求解,在不同的锥底和环板半径比例、不同的扁壳锥度下,分析和讨论了载荷与中心无量纲挠度之间复杂的非线性关系.这种关系反映了一类组合构件在力学性质上与其组成元件显著不同的特点.

Large deflection of structure composed of thin annular plate and shallow conical shell subjected to lateral and temperature loads |
| |
| Abstract: | The axisymmetric large deflection of a category of structure composed of a thin annular plate and a shallow conical shell under the action of temperature and uniform transverse loads is studied, and numerical solutions of the structure with simply supported and clamped boundary conditions are obtained with shooting method. Nonlinear relations between load and the central dimensionless deflection of the structure with various ratio of the base radius of the conical shell to the radius of the annular plate and various semivertex angles are analyzed and discussed. These relations show that the mechanical properties of the structure are remarkably different from its components. |
