Abstract
The stiffening rings position for conical shell subjected to external pressure with finite element simulation combined with the equivalent method and the equivalent method Ⅱare discussed in detail .A simple solution for the best position of stiffening rings is proposed based on equivalent method Ⅱ.Results show that the best supporting position for stiffening rings k is relevant to taper ratio λand the best position of supporting k ( or values of k1 and k2 ) increase with the rise of taper ratio .The best support position k value from the above-mentioned three methods is similar to each other .The results from the equivalent method and finite element simulation method are relatively close .It can be shown that maximum difference of k value is 4.9%for single support in terms of the simulated objects while the maximum difference of k1 value and k2 value is 8.5%and 1.9%respectively for double supports .Comparatively,the difference be-tween the results from the equivalent method Ⅱ and the finite element simulation is slightly bigger with the maximum difference reaching 14 .3%.关键词
