摘　　要：采用有限元程序ANSYS,选用壳单元,以大型减压转油线为研究对象,得出了转油线的结构固有频率;并用非线性方法和特征值方法对结构稳定性进行分析,得出直管段的稳定临界载荷。A 3-dimensional finite element model of large size vacuum transfer line was developed by us of the shell element supplied in ANSYS.The natural frequency of the structure was obtained.By using the method of eigenvalue analysis and nonlinear analysis,the structure stability was analyzed, and the critical load of straight pipe was,then,obtained.
