摘要
本文利用作者分析得到的矫形网格扁壳结构的非线性基本控制方程,采用双重Fourier级数求解了该类结构的非线性问题。推导得到了外载与结构(中心)节点横向位移之间的三次非线性关系式。并作了算例分析,给出了结构产生失稳跳跃的条件。
Based on the nonlinear governing equations of reticulated shallow shell structures obtained by authors, this paper presents a solution of nonlinear problems of bending and buckling of such kind of structure, using double Fourier series. In the investigation, the nonlinear cubic equation linking the transverse displacement of the centralj oint of the shell with the external loads has been deduced. Numerical examples are given to display the condition that snap-through buckling for the shell structurej ust occurs.
