摘    要:本文进行了加肋锥-环-柱组合壳应力、稳定性模型实验,并运用分区样条等参元法进行了数值计算,计算结果与实验结果吻合良好。还将加肋锥-环-柱组合壳与相应加肋锥-柱组合壳应力、稳定性特性进行比较。研究结果表明,加肋锥-环-柱组合壳是锥壳与柱壳间一种优越的连接形式。

关 键 词:样条等参元  加肋锥-环-柱组合壳  应力  稳定性  模型实验

Abstract:This paper presents the experiment of stresses and stability of a ring-stiffened conetoroid-cylinder combined shell. Subregion, isoparametric spline element analysis is carriedout to compare theoretical results with experimental ones. The both are in good agreement. The stresses and stability of ring-stiffened cone-toroid-cylinder combined shell arecompared with those of ring-stiffened cone-cylinder combined shell. It is shown that thering-stiffened cone-toroid-cylinder combined shell is an ideal transition structure betweencone and cylinder.
Keywords:Isoparametric spline element  Ring-stiffened cone-toroid-cylinder combined shell  Stress  Stability  Model experiment
