摘要
本文采用Donnell型扁壳理论,利用能量变分法分析了在均布外压作用下连续玻璃纤维缠绕复合材料截顶圆锥壳体的稳定性问题,得到了临界载荷的近似解析表达式。数值结果表明,临界载荷的理论预示值与实验结果非常吻合。本文所得结果对现代工程结构设计具有重要参考价值。
Based on the Donnell flat shell theory,the stability of continual glass fibre winding composite truncated cone under uniformly distributed external loading are analysed with energy variational methodjthe apprximate expression of critical load are obtained.The result shows that the theory calculated value of critical load tallies with the experiment result . The results of this paper are the important reference to modern engineering structure design.
