摘要
本文用变厚度板壳大挠度理论的修正迭代法,对周边夹紧固定、在均布载荷作用下的变厚度扁圆薄锥壳大挠度问题进行了求解,得到了精确度较高的二次近似解析解。本文结果可退化到等厚度扁圆薄锥壳、变厚度圆薄板及等厚度圆薄板构件在均布载荷作用下的非线性弯曲问题的相应结果。
In this paper, by using the modified iterative method of large deflection theory for plates and shells with vartiable thickness, the large deflection problem of shallow conic thin shells with variable thickness subjected to uniformly distributed loads is studied under the clamped edge boundary conditions, and a second-order approximate analytical solution with higher accuracy is obtained. The results given in this paper can be degenerated to those of the nonlinear deflection problems of shallow conic thin shells with uniform thickness, circular thin plates with variable thickness , and circular thin plates with uniform thickness under the action of uniform distributed loads.
