Abstract:

Braking system is important in any automobile. It is essential to decelerate the vehicle and stop it. Friction braking system is widely used system of braking. It makes use of frictional force to safely retard the vehicle. The temperature of the brake pad (stator) and disc (rotor) increases because of frictional force between them. Higher temperatures may lead to fading of brakes resulting in its failure. This paper briefly reviews published works on studying the wear and thermal characteristics of brake pads and on various available brake cooling methods. The microstructural changes in the br

A thermal engineering design project involving simulated cooling of vented and nonvented disk brakes is described. A heated copper tube was rotated in a manner that replicated the motion of a single vented passageway inside a disk brake rotor. The class assignment required design and construction of equipment, and data reduction using the lumped heat capacity method to obtain heat transfer correlations. The seven student groups plus the author produced 238 data points which were collectively correlated into two Nusselt number curves. The curve for the nonvented brakes simulation was benchmarke

Braking system is one of the important control systems of an automotive. For many years, the disc brakes have been used in automobiles for the safe retarding of the vehicles. During the braking enormous amount of heat will be generated and for effective braking sufficient heat dissipation is essential. The thermal performance of disc brake depends upon the characteristics of the airflow around the brake rotor and hence the aerodynamics is an important in the region of brake components.

Design of the brake disc geometry for a given brake disc material provides an opportunity for improvement in the fatigue life of the brake disc. High thermomechanical loads at braking lead to substantial local plastification and also induce tensile residual stresses in certain areas of the brake disc.

Purpose The braking system on motorcycles is of vital importance, taking into account that its operation is based on the friction between the surfaces in the contact that are found heat and, therefore, the brake liquid, the thermoelastic deformation on the contact surface, the degradation and failure of the material, as can be attributed to the safety of the occupants. The purpose of this paper is to perform mathematical calculations regarding the phenomena of the transfer of heat generated in the brake system.

Abstract:

A heightened awareness of the importance of natural convective cooling as a driving factor in design and thermal management of aircraft braking systems has emerged in recent years. As a result, increased attention is being devoted to understanding the buoyancy-driven flow and heat transfer occurring within the complex air passageways formed by the wheel and brake components, including the interaction of the internal and external flow fields. Through application of contemporary computational methods in conjunction with thorough experimentation, robust numerical simulations of these three-dimens

Abstract:

The presented article picks out brake particle emission testing as a central theme. Those emissions are part of the so-called non-exhaust emissions, which play an increasing role for particle emissions from transportation. The authors propose a laboratory test setup by using a brake dynamometer and a constant volume sampling approach to determine the emissions in regard to the particle number concentration. Several impacts were investigated while the same test cycle (novel worldwide harmonized light vehicles test procedure (novel-WLTP)) was applied. In a first item, the importance of the beddi

Abstract:

The brake system is a critical component for any passenger vehicle as its task is to convert the kinetic and potential energy of the vehicle into heat, allowing the vehicle to stop. Heat energy generated must be dissipated into the surroundings in order to prevent brake overheating. Traditionally, a lot of experimental testing is performed to ensure correct brake operation under all possible load scenarios. However, with the development of simulation techniques, many vehicle manufacturers today are looking into partially or completely replacing physical experiments by virtual testing. Such a t

Due to the poor conditions of wet brake cooling and the high temperature of the working characteristics, this paper intended to introduce the oil film vadose between the brake linings, considered the variation of volume of grooves on the friction plate, and then proposes the three-dimensional transient dynamic response of fluid-solid coupling mathematical model. By numerical analysis of the disc transient thermal stress field distribution on the friction plate, the friction surface temperature field variation is obtained. Finally, the results shows that the mathematical model is effective and

Abstract:

This paper develops a three-dimensional (3D) thermal-structure coupling model, implements transient stress analysis of thermoelastic contact of disk brakes with a frictional heat variation and identifies the source of the thermal fatigue. This thermostructure model allows the analysis of the effects of the moving heat source (the pad) with a variable speed and integrates the heat flux coupling between the sliding surfaces. To obtain the transient stress/temperature fields of the brake under an emergency braking, the thermoelastic problem under this 3D model is solved by the finite element meth

Design method of hydraulic system of full hybrid transmission was analyzed. At first, oil volume flow and pressure requirement was confirmed according to the vehicle control strategy. Mechanical gear pump and electric pump were used to supply oil flow for all driving modes. Self-adapted pressure regulation circuit was designed to supply high pressure oil for brake engagement. Structure dimension of valves and cooling orifices was designed by theoretical calculation. Cooling flow can be distributed proportionally among electric motors and planetary gears.

Abstract:

A computational model for the heat generation and dissipation in a disk brake during braking and the following release period has been formulated. The model simulates the braking action by investigating the thermal behaviour occurring on the disc and pad surfaces during this period. A comparative study was made between grey cast iron (GCI), asbestos, Aluminium metal matrix composite (AMC), and aramid as brake pad and disc materials. The braking process and following release period were simulated for four material combinations, GCI disc and Asbestos pad, GCI disc and Aramid pad, AMC disc and As
