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.
