摘　　要：利用有限元软件ABAQUS对激光熔覆成形的过程进行了数值仿真模拟,建立了激光熔覆成形温度场的传热数值仿真模型,并对仿真结果进行了分析。进行试验验证,预测结果与试验测量结果能较好的吻合,最大误差不超过8%,这表明所建温度场数值仿真模型合理。因此可用该数值仿真模型分析激光熔覆工艺参数对温度场的影响,以及模拟计算熔覆层的高度和重熔深度,从而为激光熔覆成形的应用提供了理论和技术支持。Make a numerical simulation about the process of＂ laser cladding forming through the finite element software-ABAQUS in this paper, and establish numerical simulation model of heat transfer about the temperature field of laser cladding forming, then analyze the simulation. By way of test verification, conclude that the predicted results can match with the test results comparatively better, with the maximum error is less than 8%, which indicates the simulation model of temperature field is reasonable. Therefore, it can use this numerical simulation model both analyze how the parameters of laser cladding affect the temperature field and simulate the height of cladding layer and the depth of remehing, thus provide a theoretical and technical support for the application of laser cladding forming.
