基于商用有限元分析软件MSC.Marc,通过对工具转动渐近成形(Rotational Incremental Sheet Forming,RISF)过程板料温度分布进行数值模拟,分析了板料在渐近成形过程中温度分布及工具转速对温度分布的影响。结果表明,工具转动渐近成形下刀过程温度分布为以工具与板料接触中心为圆心的圆形区域,工具水平移动过程的温度分布为随工具移动接触中心不为圆心的不规则圆形区域。转速虽不影响整体板料温度分布,但转速升高产生热量增多,热作用面积增大。
Based on the commercial finite element analysis software MSC.Marc, the temperature distribution of sheet metal during the Rotational Incremental Sheet Forming (RISF) process was numerically simulated, and the temperature distribution and tool speed pair Effect of temperature distribution. The results show that the temperature distribution during tool turning asymptotic forming is the circular area centered on the contact center of the tool and the sheet. The temperature distribution of the tool during the horizontal movement is the irregular circular area which is not the center of the tool moving contact center . Although the speed does not affect the overall temperature distribution of sheet metal, but the increase in speed increased heat, increased thermal area.
