THE HEATING OF A DIAPHRAGM SPRING USING INDUCTION TECHNIQUE: PARAMETRIC MODELING

The configuration and work of a system for local heating of a diaphragm spring by induction technique have been studied. The problem-oriented 3D model developed using ANSYS APDL, made possible to analyze effects of geometric, electrical and positional parameters on temperature distribution over the considered product in its electromagnetic heat treatment. In particular, the temperature fields were obtained varying spring finger's number and length, as well as a control of a finger's bend with setting up a heating mode. The main connections between the final temperature distributions and the geometry of the heated product were established. The heating was generated using both longitudinal and transverse magnetic fields.
