文中着重分析了结合边上无加固环和有加固环的锥筒结合壳抵达极限状态时的变形特点，实验指出：对于尖锥（γ＜３０°）和长筒（Ｃ２１）的结合壳，结合边的局部加强效应对壳体的极限载荷值没有多大影响，对于扁锥（γ＞４５°）和长筒的结合壳，局部加强对锥壳部分的极限承载能力有一定影响，但是，对所有的结合壳，当抵达极限状态而开始流动时，结合边上几乎不作径向位移（ｗ＝０），壳体相当于两上各自独立的圆锥壳和圆筒壳。因此，可视半锥角γ和圆筒壳长度２Ｌ的不同，以其极限承载能力较低者作为结合壳的总体极限承载能力，其相应的理论公式己由文献［１－２］给出。 除了无加固环的扁锥长筒结合壳，理论计算和实验结果符合良好。
In this paper, the deformation characteristics of the cone-shell combination shell without reinforcement ring and reinforcement ring when it reaches the limit state are analyzed emphatically. Experiments show that for the combination shell of the cone (γ <30 °) and the long tube (C21) The local strengthening effect of the edge has little effect on the ultimate load value of the shell. For the combined shell of the flat cone (γ> 45 °) and the long tube, the local strengthening has an impact on the ultimate bearing capacity of the cone shell. However, Of the conjoined shell, when it reaches the limit state and begin to flow, almost no radial displacement (w = 0) on the combined edge, the shell is equivalent to two independent conical shells and cylindrical shell. Therefore, the difference between the visible half taper angle γ and the cylindrical shell length 2L, with the lower ultimate bearing capacity as the ultimate ultimate bearing capacity of the bounding shell, is given by the reference [1-2]. In addition to the non-reinforced ring flat cone long cylinder combined shell, the theoretical calculations and experimental results in good agreement.
