| Abstract: | The squirm of the metal bellows in the field of aerospace,aviation,precision instrumentation,as well as large-scale engineering structures are the key technical indicators,and research difficulty.To solve this problem,this paper applying MSC.Marc software to research the column squirm of the typical U-shaped bellows,study the limit squirm pressure and deformation laws,etc.Verified by test,the analysis accuracy of finite element method is better than the engineering method.Combine the finite element method and engineering design with test of applications,to column squirm research the bellows,it can significantly to mention improve the design accuracy,accelerate research process,reduce research costs,and thereby improve the overall performance and market competitiveness of the products. |
| Keywords: | metal bellows finite element method column squirm non-linear test |
