Three-dimensional Numerical Study on Temperature Field of Laser Bending of Sheet Metal

摘要

Laser bending of sheet metal is a flexible forming technique by using laser scanning. Based of temperature gradsmechanism, the temperature field of sheet metal bending process by using single laser scanning is studied with theANSYS soft. A finite element model of temperature field is built. The dynamic variation process and distributionof temperature field of laser bending at given parameters are analyzed. Furthermore, the influence parameter on thepeak temperature and temperature grads are also studied.
