有环壳过渡段的锥-柱组合壳的应力和稳定性

Stresses and Stability of Cone Cylinder with Toroidal Transition

用解析方法计算了受静水外压载荷作用的有环壳过渡段的锥—柱组合壳中的应力值，并用瑞利法计算了其失稳临界载荷。计算结果说明，利用环壳过渡值锥—柱壳形成光滑连接，可使连接部位的局部应力值显著降低。

Stresses in cone cylinder shells with toroidal transition inserted are investigated by an analytical method, and buckling pressures for the shells are presented by Rayleigh Ritzs method. The numerical results show that smooth transition formed by inserting the segment of toroidal shell will reduce local stresses in cone cylinder shells sharply, and increases the buckling pressures of the shells comparatively.
