Firstly, the simulation scheme is formulated for the numerical simulation of double frequency induction heating of bevel gear, the problems in the numerical analysis are assumed and technically treated, and the three-dimensional finite element model suitable for induction heating analysis is established by using ANSYS software.
According to the structural characteristics of bevel gear and the design principle of induction coil, the structure of induction coil is determined, and its parameters are optimized. It is clearly pointed out that the tooth height of induction coil and the spacing between induction coil and tooth root affect not only the induction heating efficiency of bevel gear tooth root, but also the stable value of tooth root temperature.
The realization mode of dual frequency induction heating is explored, and the segmented dual frequency induction heating method is determined. The numerical simulation of the electromagnetic thermal coupling process of dual frequency induction heating is realized by using APDL language, the characteristics of skin effect in the induction heating process are explored, and the temperature field of bevel gear dual frequency induction heating process is dynamically analyzed.
