摘要

为了得到适合于直角法兰双棍夹持扩旋成形模拟的有限元模型

基于ABAQUS/Explicit平台

针对常用的工件转动与不转动的建模方法

建立了2种直角法兰双辊夹持扩旋成形有限元模型.利用这2种模型对旋压成形过程分别进行了数值模拟

从旋辊轨迹、动态效应、计算时间、计算结果等方面比较分析了2种模型对双棍夹持扩旋成形模拟的影响.数值模拟结果表明

工件转动模型得到的最大等效应力应变偏大

而采用工件不转动模型不仅可以提高计算精度

而且可有效地降低计算时间

因此最终确定工件不转动模型为所研究的最佳有限元模型.

Abstract

To obtain the reasonable model of double rollers clamping expanding spinning

based on ABAQUS/Explicit

two models are established in case of unrotating rotating workpiece. Following the two models

the forming process for right-angle flange is analyzed. And then the effects of two models on simulation are investigated in terms of roller path

dynamic effects

computing time and computing results. Compared with the model for rotating workpiece

the model for unrotating workpiece enables to improve the calculation accuracy and shorten computing period. Although stress and stain distributions of the two models are similar at the same place of the workpiece

the equivalent stress and strain values obtained from the model for rotating workpiece get greater. It is verified that the model for unrotating workpiece is the optimal one to simulate double rollers clamping expanding spinning process with finite element method.
