Abstract

In the paper* has been presented non-linear mathematical model of heat flow in a discrete object during burnishing rolling operation with the electrocontact heating. The model has been derived by the method of elementary balances. This paper presents algorithm of numerical solution of the model and gives results exemplifying numerical calculations 1 Heat phenomena During roller burnishing there are four stages of field variations, i.e. field building up, nearly steady state, equalisation and decrease*. Field building up occurs at the first stage of burnishing, at the moment of starting sources operation. Decrease in field intensity takes place during th
