Description
Summary:In industrial machinery, thermal expansion can change the geometry of mechanical components, particularly the operating clearances and the characteristics of materials. This may result in overloading and dangerous tightening. In addition, intense heat flux through thick walls deforms parts and cause thermal stresses. The heat alters also the mechanical and the tribological properties of materials; it lowers their resistance and their modulus of elasticity. These phenomena require the limitation of temperature and heat flow and the dimensioning of the members accordingly. It is therefore of very high importance to determine the temperature field in the interfacial sliding contacts. Since it is difficult to measure these temperatures, it seems important to use developed models with experimental investigations in order to improve the understanding of the phenomena and to determine the temperature distribution in and near the contact zone. The objective of this work is to determine experimentally the temperature
