Numerical simulation and investigation of induction system for hardening of internal combustion engine camshaft

Abstract

This paper describes the numerical simulation and investigation of the electrothermal processes in the induction system for hardening of cams and journals of camshaft. Hardening of the camshaft elements is carried out by one simple inductor of round shape due to shift of the camshaft axis inside it. During the process of the hardening of the cams, the camshaft is stationary, during the process of the hardening of the journals it rotates. The results of the investigations are presented in the form of the temperature distribution in the cam and the journal. The optimum parameters of the induction system are also given, at which the best temperature distribution in the elements of the camshaft is achieved.
