摘要
采用有限元方法实现了激光弯曲成形多次重复扫描过程的仿真。研究了板料上下表面的应变、温度等随时间的变化规律,结果表明:板料的弯曲角度与扫描次数间基本保持线性关系,而且第一次扫描板料产生的弯曲角度最大。
The simulation of multiple scanning process for laser bending of sheet metals is carried out by using FEM method. The rules of the temperature and the stress-strain on the upper and lower surfaces of the sheet varying with the times are investigated, and the results show that the relationship between the number of scans and the bending angle is about in direct ratio. Moreover, the bending angle induced by the first irradiated time is the largest.
