带框架肋骨的环肋圆柱壳的总体弹性屈曲

求解带肋圆柱壳屈曲压力的方法有很多,至今为止大部分人都把目光集中到了以电能量法来求解,因为用其它方法计算加强圆柱壳的屈曲压力是非常困难的.解决大圆柱壳大分舱结构的一个关键问题是求解带框架肋骨的环肋圆柱壳的总体屈曲.为此,提出一种计算带框架肋骨的环肋大圆柱壳总体弹性屈曲能量的方法.

General Elastic Buckling Problem of Ring-Stiffened Circular Cylindrical Shells with Heavy Frames

There are a lot of candidate methods for working out the buckling pressure of ribbed cylindrical shell, but so far the one which attracts attention most is the energy method, because calculating the buckling pressure of stiffened cylindrical shell with other methods are very difficult. To comprehend general buckling of ring stiffened circular cylindrical shells with heavy frames is the key to solve the problem about the large cabins with high subdivision structure of circular cylindrical shell. In view of this, the paper puts forward the energy method of solving the general elastic buckling problem of huge ring-stiffened circular cylindrical shells with heavy frames.
