Electromagnetic field models´ building and simulation in workpiece of inductive disassembling of bearing inner race

Based on researching the shaft bearing replacer, this paper built the models of electromagnetic field and eddy current density in bearing inner race being induction heating. The regularities distribution of the electromagnetic field and eddy current density had been simulated by the software Matlab, the results of simulation not only proved the existence skin effect but also provided theory evidence for designing and researching of the shaft bearing replacer. The correctness of the models and simulation had been verified indirectly by testing the temperature on different isothermal surface of the bearing inner race.
