摘要
基于ANSYS的激光熔覆成形温度场数值模拟可以真实再现熔覆工艺全过程,为优化工艺参数和预测成形缺陷提供可靠的理论依据。本文系统总结了ANSYS在熔覆成形温度场数值模拟中的应用;深入分析了有限元模型的建立、网格划分、热源形式及动态实现、熔池对流、材料动态增长描述等关键问题的处理方法;指出了ANSYS在熔覆成形温度场数值模拟领域应用中存在的问题,并在此基础上提出了今后的发展方向。
Temperature field numerical simulation of laser cladding forming （LCF） based on ANSYS can really reappear the whole cladding process, which can supply the reliable theoretical base for optimizing processing parameters and forecasting forming flaw. The application of ANSYS in temperature field numerical simulation of laser cladding forming was generalized systematicly in this paper, the processing methods of key problems such as the establishment of the finite element model, meshing, thermal resource determination and dynamic handing, molten pool convection and material dynamic increasing were analysed profoundly. The problems of ANSYS applying in LCF finite element simulation were pointed out and the important development direction was presented on this basis.
