This article is concerned with frictional heating phenomenon playing a central role in disc brake (clutch) systems performance. It was of great interest to carry the description of existing numerical solutions of the problem. The level of the calculations was categorized into three problems. The first is a common approach, drawn primarily on the assumption that the heat flow rate generated at the disc/pad interface is a known quantity. Heat generation was substituted by the intensity of heat flux depending on contact pressure, coefficient of friction and evolution of angular velocity, and radius of the disc product. A more complex description of the braking action was given by the assumption of mutual relation between mating parts of the disc brake system. In this case, the thermoelasticity theory was applied to the model. The facts of existing critical speed is established, in which hot spots caused mainly by contact pressure variations frictionally-excited thermoelastic instability phenomenon entered co...

The FEM-Modeling of the Frictional Heating Phenomenon in the Pad/Disc Tribosystem (A Review)

The heat partition ratio is an important input parameter in simulation carried out by the finite element method (FEM) of the transient temperature fields in such elements as brakes, a pad, and a disc. Therefore, the aim of this article is to study the influence of nine various (experimental and theoretical) formulas for heat partition ratio on temperature in a pad/disc tribosystem. The real dimensions, operating conditions, and thermophysical properties of materials of two different disc brake systems were adopted for the finite element analysis. The evolutions of the temperature on the contact surface of the pad, obtained for different heat partition ratios, are compared with corresponding experimental data. The results revealed a significant influence of heat partition ratio on the evolution of pad maximal temperature, whereas the disc contact temperature was reasonably stable and coincided with most cases under consideration.
