摘要
在分析温变材料物性参数的基础上,采用ANSYS有限元软件作为分析平台,构建感应熔覆过程的三维热场有限元分析模型。对三维与二维模型的建模结构与热场分布,探讨多维度数值模拟计算结果的差异。研究结果表明:在相同的感应熔覆数值模拟参数设置下,三维模型的热场温度高于二维模型的热场温度;三维模型的径向热传导高于二维模型,二维模型的轴向热传导高于三维模型;随着加载电流密度的逐步增大,三维与二维模型的温度差加大;相对二维模型,三维模型温度场分布受辐射的影响较为显著。研究结论为感应熔覆多维度数值模拟建模与计算提供了应用参考。
Based on the analysis of physical parameters of temperature change material, ANSYS finite element software as the analysis platform, three dimensional finite element model of thermal field is built. Comparing the modeling units and the thermal distribution of three dimensional and two dimensional models, the results of the multi-dimensional number simulation are investigated.The results show that under the same induction cladding numerical simulation parameters settings, three-dimensional model of thermal field temperature is higher than the two-dimensional model of thermal field temperature; three-dimensional model of the radial thermal conductivity is higher than two-dimensional model; the two-dimensional model of axial heat conduction is higher than three-dimensional model; with the increasing load current density, three-dimensional and two-dimensional model of the temperature are different in the process of increasing;Comparing with two-dimensional model, the affect of radiation for the three-dimensional model of temperature field distribution is significant.Research conclusion for induction cladding multidimensional modeling and numerical simulation calculation provides application reference.
