Finite element analysis to the multi-layer U-shaped bellows' strength and axial stiffness

摘要

The multilayer U-shaped bellows' strenth and axial stiffness are studied by ANSYS finite element analysis. The plane axisymmetric model of multilayer bellows is established, and the material nonlinear, geometric nonlinearity and contact between the layers of multilayer bellows is considered, obtained some useful conclusions. And the analysis results are compared with the results calculated by engineering approximation method, indicating that the ANSYS finite element results closer to the actual situation, there are some errors when using the engineering approximation method analysis multilayer bellows.
