Peculiarities of mathematical modeling of induction heating of details for thermal assembly and disconnection of connections

Abstract

One of the most common ways of assembling and disassembling connections with interference is a thermal method with inductive action. To separate the connection elements using induction heating, it is necessary to heat the female part so that it heats up faster than the male member. This requires matching the intensity of heating with the rate of heat propagation in the material and heat transfer between the parts. Since the connection with the interference has significant differences, both in the shape of the parts and in the place of their location in the machine, the creation of a mathematical model of induction heating, taking into account the characteristics of parts and compounds, as well as the parameters of the electromagnetic field, significantly reduces the experimental part of the process designing, as well as improve the quality of the products. The papers consider aspects and give recommendations on mathematical modeling of thermal and electrical processes that occur during induction heating.
