| Abstract: | There are many forms of vertical pipeline,so it is difficult to build a universal finite element model.During the installation,the strength of lifting vertical pipeline must be considered.Based on ANSYS’s redevelopment language,the special module of the lifting of vertical pipeline is developed.The interfaces are made by using UIDL and the parametric commands are programmed by APDL.The function of establishing multiple forms of vertical pipeline and strength analysis is achieved,the singularity of stiffness matrix is solved in the computational process.The engineering calculation results and those obtained by use of other softwares show that the program of lifting of vertical pipeline based on the ANSYS’s redevelopment language is reliable. |
