With the complication of the three-dimensional geometry of the aerial tube and the increasing requirements of the manufacturing precision, the application of the finite element analysis method to study the optimum bending process has become a universal choice. In this paper, the forming principle of typical tube bending forming process is studied, and the evaluation index of tube bending performance is analyzed. To improve the efficiency and reduce the difficulty of using the finite element analysis in the tube bending, the user defined interface of the bending tube forming based on the ABAQUS general finite element analysis software platform is developed by using the Python programming language. It provides both preprocessing and post-processing functions of the rotary draw bending and free tube bending. By analyzing the finite element analysis results of tube bending, it can automatically calculate the evaluation index of tube bending and produce the analysis report.
