| 摘 要： | 根据张力减径过程的变形特点,采用组元建模技术,编写了弹塑性有限元计算程序。利用AutoCAD进行图形后处理,并通过VB建立人机交互界面,开发了管材张力减径过程快速仿真系统。研究了管材张力减径的变形过程,预报了轧后产品几何形状、应力、应变等分布状态。模拟结果与生产实测结果吻合良好,表明该系统能够胜任钢管张力减径过程模拟及产品质量预报工作。

| Abstract: | Based on the characteristics of tube stretch-reducing process, the elastic FE calculation program is prepared by means of the constituent element modeling technique. After graphic processing with AutoCAD and setting up of man/machine interaction interface via VB, the quick simulation system for tube stretch-reducing pro- cess is developed. With the said system, the deformation process during tube stretch-reducing operation is studied,resulting in the forecast of distributions concerning geometry, stress and strain of the rolled product. The simulation result is in compliance with the measurement result of relevant actual operation process, which means that the newly developed system is capable of simulating steel tube stretch-reducing process as well as forecasting product quality. |
