中文摘要:为了研究单道激光熔覆薄板的温度场分布,采用仿真与实验对照的方法,利用ANSYS软件,通过高斯热源模型模拟激光光束能量,再采用非线性边界设定,对单道激光熔覆及冷却过程的温度场进行仿真;使用2kW光纤激光器将铁基(Fe60)粉末熔覆在2mm厚T9A钢板上,并用热成像仪测量多样点温度。结果表明,激光熔覆薄板温度场的仿真符合实验验证结果,其最高温度的最大误差为8.31%。此研究结果对激光加工参量优化有一定指导作用。
外文摘要:In order to study the temperature field distribution of single-channel laser cladding sheet,a Gaussian heat source model was used to simulate the energy of laser beam through ANSYS software,and the temperature field of single-channel laser cladding and cooling process was simulated by using nonlinear boundary setting.A 2kW fiber laser was used to cladding iron based(Fe60)powder onto a 2mm thick T9A steel plate,and the temperature at various points was measured by a thermal imager.The results show that the simulation results of temperature field of laser cladding sheet accord with the experimental results,and the maximum error of its maximum temperature is 8.31%.The research results are useful for the optimization of laser machining parameters.
