Abstract:
In the present study, the analysis method of critical pressure of reinforced s-shaped bellows was carried out based on the theoretical and numerical simulation analysis.Firstly, the axial stiffness of reinforced s-shaped bellows was obtained based on the finite element method.The bending stiffness of bellows was obtained according to the minimal axial stiffness.Then, boundary influence coefficient of bellows was analyzed based on axial control equation of thin walled cylinder under the inner pressure.At last, the analysis method of critical load of reinforced S-shaped bellows was put forward based on Euler equation and EJMA, which takes plasticity, inner pressure and boundary condition into account and actually reflects the bellows condition.It can be well used in the buckling analysis of reinforced S-shaped bellows.
