Abstract

In this paper, buckling analysis was performed by numerical analysis method to analyze the influence of initial transversal displacement of pipelines on the critical buckling load. Firstly, buckling solution was obtained by the eigenvalue method, and buckling modal was established and taken as the basic input parameter of initial displacement. Secondly, based on the geometric parameters of pipelines, a pipeline model was set up by ANSYS finite element software. And finally, nonlinear large-deformation model was solved and the influence of initial transversal displacement on the critical buckling load of pipelines was analyzed. It is shown that the initial transverse displacement is negatively correlated with the critical buckling load of pipelines and their relationship is nearly linear. The larger the initial transverse displacement is, the lower the critical buckling load is. The research results can provide the technical support for pipeline design and engineering construction in the future.
