| Abstract: | Based on the finite element analysis software ANSYS10.0,a coupled thermo-mechanical three-dimensional model of brake disc is built.Transient temperature field and stress field of three different structures of brake discs(solid,ventilating slot and ventilating slot & vent) are simulated and analyzed.It aims to analyze the thermodynamics characteristics of three different structures of brake discs in the emergency condition of the velocity-60 km/h.Stimulation results show that the distribution tendencies of t... |
