Abstrakt EN: Computer modelling of assembly and disassembly of structural parts that are coupled with interference fit by means pf induction heating is a rather complicated task. Besides three physical fields, we have to solve also the thermocontact problem. The paper solves the tast in quasi-coupled formulation as an electrothermoelastic problem in 2D arrangement. Its solution is based on time stepping with built-in internal iterative processes fore improvement of accuracy of parameters of linearized equations describing all three involved fields that are in each time illustrated on an example of fixing and disassembly of a drill in chuck. Considered are real characteristics such as radial interference between the drill shank and chuck, power of the inductor, physical parameters of used materials, conditions of cooling and other quantities responsible for reiable operation of the system.
