| 摘 要： | 对旋转组合壳体在轴对称静载荷作用下的强度计算,采用了性能良好的三节点曲线壳元,并采用整体坐标下位移和转角各自独立的插值函数推导有限元列式和编制计算机程序。经算例验证表明,上述单元和算法具有单元划分少、精度高、收敛性好的优点。对锥-锥-柱、锥-环-柱、锥-环-锥-环-柱等组合壳过渡区域最大弯矩值和应力值随结构参数变化情况进行了广泛的计算和对比分析,得出了一些有重要工程意义的新结论。

| Abstract: | In this paper three-node curve element is adopted for the elastic strength analysis of combined revolutionary shell. The finite element formulas are deduced. The computing results are compared with results of other methods. The maximum moments and stresses of a series of combined shells, such as cone-toroid-cylinder shells, cone-cone-cylinder shells and cone-toroid-cone-toroid cylinder shells are compared. Some new important conclusions are proposed |
