ABSTRACT

A three-dimensional thermo-mechanical coupling finite element model of a solid disc brake is established for a certain type of vehicle to analyze the thermo-mechanical coupling characteristics of the brake disc and the friction pad under emergency braking and slow braking. The temperature and stress fields of the solid disk brake are simulated under the two braking modes to obtain the distribution characteristics of the temperature and stress fields of the brake, and the interaction between the temperature and the equivalent force is discussed. The results show that the slow braking condition is more likely to cause the phenomena of elevated temperature and equivalent force than the emergency braking condition. In addition, a three-dimensional finite element model incorporating the thermal-mechanical coupling effect is developed for analyzing the transient behavior of solid disc brake systems under emergency and progressive braking conditions. The model embodies the coupled thermal stress interactions between the brake disc and the friction pad, and simulates the spatial and temporal evolution of the temperature and von Mises stress field during braking.
