Assembly and disassembly of pressed joints by means of induction heating

摘要

The paper deals with the solution of the induction heating in common with the corresponding thermoelastic stresses and deformations in axi-symmetric bodies that is applied to weakly of assembly and disassembly of the hot-pressed joints. The task in formulated as a weakly coupled problem. Its mathematical model, that is based on differential equations and boundary conditions describing the distribution of the primary time dependent electromagnetic field, consequent non-stationary temperature field and finally the field of the thermoelastic displacements, is then solved by the FEM-based professional programs QuickField and MARC. The methodology is supplemented by an illustrative example demonstrating the possibilities of the Presented algorithm.
