doi:10.3901/JME.2022.06.202

Abstract

Abstract: With the continuous improvement of the speed of high-speed trains in China, especially the existence of long ramps, the application environment of brake disc becomes worse. Due to the heat generated by the braking friction, the temperature of the brake disc rises rapidly. If the heat dissipation is not timely, high thermal stress will be formed, which leads to the generation of thermal fatigue cracks. Therefore, the efficient brake disc heat dissipation problem is particularly important. At present, the heat dissipation design of the brake disc is mainly adopted to change the structure form of the heat sink, which has certain limitations in the heat dissipation effect. To further reduce the braking temperature and thermal stress of the brake disc, according to the principle of phase change heat storage, the cooling structure of the brake disc is designed, and the temperature of the brake disc is increased by two consecutive emergency braking. Finite element analysis software is used to analyze the heat dissipation of different phase change heat storage materials, and the temperature and stress fields of three brake discs are obtained. The results show that the brake disc with phase change heat storage material can significantly reduce the maximum temperature of the brake disc during braking. These materials can reduce the temperature gradient of the brake disc so that the thermal stress on the brake disc is reduced. To a certain extent, the occurrence of thermal fatigue cracks is prevented.
