“…Even for slow moving, the disk still can be treated as semi-infinite model. 3. If the heat source moves slowly (Pe \ 10), the cooling effects can decrease the surface and midplane temperatures significantly.…”

The thermal problem of plate slides against symmetrically located contacting pads is investigated. The aim is to find out the influences of plate thickness, moving speed, and convection on the temperature field of the plate. Proper models and computing methods for specific situations can be determined based on these analyses. Finite element method of moving heat input is used to calculate the temperature field which is validated by comparing with some existing analytical solutions. The results show that the characteristic time for the steady state of temperature can be approximated exponentially as a function of moving speed. If the plate is thinner than the critical thickness, the surface temperature is increased significantly, which means that the temperature field is very sensitive to the plate thickness in this situation. The increasing moving speed increases the peak surface temperature almost linearly, and the convection outside of the contact area can decrease the peak surface temperature significantly if the heat sources move slowly, while it hardly affects the peak surface temperature if the heat sources move fast. Based on these results, the criterion of choosing a model and computing methods for studying the temperature fields in the similar structures is established.

“…It has a friction track of 17 mm in width and 22 mm in thickness. The size and shape of the pad and the disc are compromises based on the geometries used on real pad and disc of real braking situations [20]. Pin and disc mass temperatures are measured by thermocouples located 2 mm under the contact surface on the mean friction radius.…”

“…It does not allow determining a true surface temperature due to changes in the surface emissivity by wear, oxidation and movement of the third body [20]. However, the variation of the luminance provides relevant information about thermal phenomena of load-bearing localizations affecting rubbed surfaces.…”

“…For example, predicting the lifetime of a mechanical component like a bearing, blade disk or brake system must take into account 6 both the dynamic analysis of the mechanism up to its end-of-life and knowledge of the local transformations of the bodies in contact (local deformations [15,41], surface degradation [42,43], etc. ).…”

Tribologists are confronted on a daily basis by the need to understand the causes and consequences of friction on the behaviour of bodies in contact. Understanding contact behaviour is not only a scientific curiosity but the key to solving numerous industrial issues. Numerical tools have been developed to overcome the problems encountered in experiments due to limitations in the local dynamic analysis of multi-scale systems (mechanisms, bodies in contact, interfaces). More than an exhibition of numerical results, the present paper proposes reviewing the literature on the numerical tribology of dry contacts by analysing the different scales involved. © 2011 Elsevier Ltd.
