An Optimal Frequency Condition for An Induction Hardening for An Axle Shaft using Thermal-Electromagnetic Coupled Analysis Choi, Jin Kyu; Nam, Kwang Sik; Kim, Jae Ki; Choi, Ho Min; Lee, Seok Soon;
High-frequency induction hardening (HFIH) is used in many industries and has a number of advantages, including reliability and repeatability. It is a non-contact method of providing energy-efficient heat in the minimum amount of time without using a flame. Recently, HFIH has been actively studied using the finite-element method (FEM), however, these studies only focused on the accuracy of the analysis. In this paper, we analyzed HFIH by using a variable frequency based on the conditions of the same shape and input power then comparing the analysis results to experimental results. The analysis and experimental results indicate that the hardening depths are approximately the same using the optimal frequency of 3kHz.
