The simulation calculation on the temperature field of the disc brake system on high-speed trains under the working condition of constant speed at 50Km/h is made. A steady-state calculation model is established according to the actual geometric size of a brake disc and a brake pad, and the analog calculation and simulation on the temperature field of the brake disc and the brake pad by using the large-scale nonlinear finite element software ABAQUS are carried out. The distribution rules of the temperature field of the brake disc and the brake pad under the working condition of constant speed are made known. The surface temperature of the brake disc at friction radius is the highest, with a band distribution for temperature. There exists a temperature flex point in the direction of thickness, of which the thickness occupies 15% of that of the brake disc; due to the small volume of the brake pad, the temperature gradient of the whole brake pad is not sharp, and larger temperature gradient occurs only on the contact surface.

Abstract The braking performance of the vehicle directly affects the driving safety. Because of the different number of brake pistons and the wear of the brake pads, the distribution of braking pressure will be uneven, which will affect the distribution of temperature field and stress field during braking, then affect the thermal fatigue life of brake discs. Therefore, in this paper, the static tensile and compressive tests of gray cast iron HT200 samples cut from vehicle brake discs are carried out at −25°C, room temperature (25°C) and 500°C, and the stress-strain curves are analyzed to obtain mechanical properties such as strength limit, elastic modulus and so on at the temperature. Based on these parameters, the finite element software ABAQUS is used to simulate the single emergency braking condition. The thermal-structural coupling simulation of brake disc is carried out to study the influences of uneven brake pressure distribution on the temperature and stress fields of brake disc, which lays a foundation for the thermal fatigue life evaluation of brake disc.

Braking Process

According to the real dimension of the braking disc, the finite element modeling for three-dimensional transient cyclic symmetry during the long downhill braking is established. The distribution of the transient temperature field of the brake disc during the braking are analyzed. The variation of the friction factor combined with the temperature characteristics of the friction factor during the braking are analyzed. The analysis result show: During the braking, the temperature of the brake rises increasingly and reaches the top temperature of 316.04°C at the end of braking process, the high temperature section concentrates in the far area of the friction surface; The changes of the friction factor is relatively stable during the long downhill braking. There is no obvious thermal recession. (Abstract)

With the higher speed of the car, brake disc temperature will increase sharply when emergency braking, and its performance is demanded more and more higher. According to the Heat Conduction Theory, a brake disc's Thermo-mechanical Coupling model is built using ABAQUS software to analyze the brake disc transient temperature field. The analysis results shows that there is temperature gradient along the radial direction and axial direction, the temperature of the surface nodes with braking time has a wavy change, and the simulation result can be used as the references of brake disc design and selection.

Transient heat transfer analysis of disc brake has been performed to find out an ideal shape of pad geometry. The analysis has taken frictional heat between brake disc and pads as heat flux onto the friction surface, the disc and the pad's temperature fields then were explored involving thermal conduction, forced convection and surface radiation effects. The disc thermal expansion stress was then acquired by quasi-static analysis using its temperature of aforesaid heat transfer analysis. Five prototypes of pad designs with geometry and volume variations were implemented for analytical comparison. Both pads and disc are required to have lower and uniform temperature field and thermal stress. The results uncover that heat conduction is domination in heat dissipation progress during braking, and big volume pad is cooler. Pad volume has more impact to heat transfer procedure and temperature gradient than pad geometry variation does. The design has 10 triangle pads is considered to be an ideal candidate. Its maximum disc temperature and thermal stress are the least among the five designs.
