Research progress of temperature field calculation of disc brake braking interface based on numerical analysis

Abstract

Disc brakes are the most widely used key components in the braking system of various types of machinery and equipment. When it works, it converts kinetic energy into thermal energy, which will make the braking interface overheat, thus leading to thermal recession of the brake disc and brake pad, which will eventually seriously affect the service life of the machine. The study of temperature changes at the working interface of disc brakes during braking is of great significance to the selection of brake friction pairs and the setting of braking parameters, and is an important theoretical guarantee for improving the service life of brakes. Currently, there are extensive researches on the analysis of temperature fields at the working interface of disc brakes. This paper summarizes the latest numerical research progress of the friction interface temperature field of disc brakes, and evaluates the research status of the friction interface temperature field model, temperature field solution method, and thermodynamics. The review finds that the current numerical method has become the most common method for conducting thermal analysis of disc brakes. The finite element analysis based on thermal modeling, thermal-mechanical coupling methods, and temperature distribution is able to provide more research basis for studying the thermal failure of brake friction pairs, thermal damage mechanisms, and friction material wear mechanisms. Improving the accuracy of the thermal model calculation will be an important research direction for the future numerical analysis of the temperature field of disc brakes.

Analysis of the tribological behavior of the high-speed and heavy-load braking interface with dynamic wear of brake pads

“…One is to combine multiple friction blocks into a uniform whole, and the feasibility of this method has been proven. 19,20 The second method involves removing the brake block that has a particular shape from the brake pad. The first simplified scheme is selected to analyze the impact of dynamic wear of the brake pad on the tribological characteristics of the brake interface of the wind turbine brake.…”

Influence of Functionally Graded Protective Coating on the Temperature in a Braking System

“…Frictional heating occurs when two contacting elements slide against each other, resulting in the conversion of mechanical energy into heat [ 1 , 2 ]. Modern braking systems operate based on this phenomenon [ 3 ].…”
