Abstract

With the continuous improvement of train speed, disc braking are widely applied due to its high-power of braking, reliable working, etc. In this paper, relative wind speed of different locations on the brake disc surface during braking has been calculated, and the equivalent wind speed coefficient is given, which is the ratio of relative wind speed and train speed. On this basis, the convection coefficient of the brake disc surface has been optimized. Its value has been reduced comparing to that before optimization. Combining the optimized convection coefficient and using finite element software ANSYS, it calculated the temperature field of brake disc based on the three-dimensional model in the emergency braking condition, the result and that before optimization were compared with experimental data.
