Abstract:
In this paper, stability of bellows is studied by means of nonlinear finite element analysis. Under the circumstances of geometric nonlinearity and material nonlinearity, a static analysis is applied to the bellows w hich are loaded w ith axial, lateral, bending displacement and internal pressure. In the process of analysis the load condition is totally imitated. In this w ay the history of its deformat ion is described, so that buckling load is determined precisely. This method precisely describes the mechanical performance of U-shaped bellow s and provides an effect ive w ay for research and design stability of bellows.
