EFFECT OF FRICTIONAL HEAT ON THE COEFFICIENT OF FRICTION DURING COMPLETE SLIDE OF AL6061-T6 HERTZIAN CONTACTS

In contact tractions, the coefficient of friction (COF) is a key factor and it alters as the contact temperature rises.Therefore, it is crucial to pay attention to how the COF and the increase in contact temperature are related. Sincefracture propagation is caused by the existence of the majority load, which can be determined by observing thecontact temperature, and crack initiation is caused by the presence of high contact adhesive friction, the transitionfrom full slip circumstances to partial slip conditions is crucial. Using K-type thermocouples adhered close to thecontact points along the vertical axis of the cylindrical pad, the contact temperature can be inferred from themeasured temperatures. In the current work, the frictional heat flow in the pad is examined during sliding. Finiteelement analysis (FEA) was used to compare the heat flow in a cylindrical pad with and without insulation. The 1-Dheat flow study of the cylindrical pad was carried out using C programming, and the accuracy of the findings waschecked against those from the 2-D ANSYS finite element analysis.
