摘要

随着航空导管空间几何形状设计的复杂化，以及对制造精度要求的不断提高，应用有限元分析方法研究最佳弯曲成形工艺已成为一种普遍的选择。研究了典型导管弯曲成形工艺方法的成形原理，分析了导管弯曲成形性能评价指标。同时，为提高导管弯曲成形有限元分析前后处理效率和降低使用难度，使用Python编程语言开发了基于ABAQUS通用型有限元分析软件平台的弯管成形用户自定义界面。开发的用户界面提供了针对导管绕弯和自由弯曲成形的自动前后处理功能，实现了导管弯曲成形性能指标的自动计算和分析报告自动生成的功能。

Abstract

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.
