基于Abaqus的旋压件壁厚的自动测量方法

Automatic Measurement Method of Wall Thickness of Spun Workpieces Based on Abaqus

针对采用Abaqus有限元软件对旋压成形进行数值模拟时,旋压件壁厚无法快速、准确获取及无法实现可视化的问题,提出对基于Abaqus数值模拟的旋压件壁厚自动测量及可视化方法进行研究。通过Python语言编写代码来实现旋压件壁厚的自动测量,并采用RSG对话框构造器定制菜单界面,开发出了基于Abaqus的旋压件壁厚自动测量工具包,实现了锥形件、带内筋筒形件等旋压件壁厚的自动测量,以及以云图的形式显示结果。通过对比采用壁厚自动测量工具及采用三维软件进行壁厚测量的结果,发现文中所开发的旋压件壁厚自动测量工具包能准确、快捷地测量各类旋压件的壁厚分布。

When the numerical simulation of spinning forming is carried out by Abaqus finite element software,the wall thickness of spun workpieces can not be obtained quickly and accurately,and the process can not be visua-lized.In order to solve this problem,a method of automatic measurement and visualization of the wall thickness of spun workpieces based on Abaqus numerical simulation was proposed.Automatic measurement of wall thickness of spun workpieces was realized through coding in Python language.Using RSG dialog builder to customize menu interface,a toolkit for automatic measurement of wall thickness of spun workpieces based on Abaqus was developed.Automatic measurement of wall thickness of conical parts,cylindrical parts with inner ribs and other spinning parts was realized,and the results were displayed in the form of contour.By comparing the measurement results with the automatic wall thickness measurement tool and the three-dimensional software,it is found that the developed toolkit can accurately measure the wall thickness distribution of various kinds of spun workpieces.
