Analysis of Transient Temperature and Thermal Stress Distribution on the High-speed Strain Brake Disk by Simulation

Features of the estimation of the intensity of heat exchange in self-ventilated disk-shoe brakes of vehicles

“…However, the heat emission intensity is not considered, which significantly reduces the accuracy, particularly at high vehicle speeds. Temperature distribution is shown and train disk brakes heat streams are analyzed [8]. But the reasons of the origins and development of thermal cracks on the disk friction surface are not reviewed.…”

Rapid prediction of brake disc temperature of high-speed train based on back propagation neural network

“…At present, the main methods of brake disc temperature prediction include bench test and finite element simulation calculation. Scholars usually establish a finite element thermal analysis model to predict the temperature change of the brake disc, and compare the bench test results to verify the accuracy of the model [4]. However, this prediction method usually requires a high time cost, and it is difficult to meet the real-time prediction requirements of the high-speed train for the brake disc temperature.…”

Investigation into Multiaxial Character of Thermomechanical Fatigue Damage on High-Speed Railway Brake Disc

“…Due to the large tonnage and high speed of a vehicle, a tremendous amount of kinetic energy is transformed into thermal energy during the actions of implementing braking, precision stopping and stabling speeding [2]. This transformation arouses significant temperature increasement and exposes the brake disc to severe thermomechanical loading, resulted from the frictional contact between the brake disc and pad [3]. Because of this, the thermomechanical fatigue damage is considerably severe [4,5] (see Figure 1), and it could be more serious in the long slope line.…”
