摘要
研究了弹性圆柱壳在任意轴对称边界条件下和受均布法向荷载作用下的稳定性优化设计问题 ,即极大化屈曲临界荷载。利用能量原理分析轴对称变厚度圆柱壳的分支点屈曲 ,将求解屈曲临界荷载变成求解广义特征值方程 ,使圆柱壳稳定性优化设计成为极大化最小特征值问题。
The present study is concerned with the optimal design of cylindrical shell on stability with arbitrary axisymmetrical boundary conditions and radial pressure under the condition of the volume being constant. The problem involves the maxi-minimal buckling pressure of the cylindrical shell. Buckling of shell is analysed by the energy principle and the problem is simply to find the maximum of eigenvalue. Numerical results show the effectiveness of the method reported.
