摘要
板料激光弯曲成形是一种利用激光成形构件的柔性成形技术 ,以平板激光单次扫描成形的过程为研究对象 ,应用有限元分析软件ANSYS进行二次开发 ,对温度梯度机理下弯曲成形过程的温度场进行了系统的研究。建立了温度场的有限元分析模型 ,研究了给定技术参数下激光弯曲温度场的动态变化过程和温度场的分布 。
Laser bending is a recently developed and highly flexible metal forming techniqu e.In this paper,3D numerical study on laser bending under temperature gradient m echanism are carried out with ANSYS software.A finite element model of temperatu re field is built,the dynamic temperature field and temperature disribution unde r provided conditions are analyzed according to the numerical sumulation trsults ,the relationships between the technique parameters and the peak temperature,tem perature gradient are investigated.
