Abstract: To research into temperature field of disc brake, as needed, a constant speed braking bench is developed to simulate the braking condition of motorcycle under long slope by similarity principle. The disc fixed on rotating shaft, which is clamped by three jaw chuck of lathe, rotate with constant speed. The disc is clamped by inner pad and outward pad though hydraulic pressure. Temperature evolution of certain point on outward pad, braking torque evolution, mean value of braking pressure, temperature evolution on the frictional area of disc are measured by thermal couple, pressure sensor, piezometer, thermal imager respectively. The braking bench could realize the dynamic test of all variables under different rational speed and different braking pressure. The maximum temperature is chosen as variable to research the evolution of friction coefficient with temperature increasing. Based on experiment, simulation and analysis are did by ABAQUS. Simulation models are made from actual model by the ratio 11, load and boundary conditions are the same as reality, the evolution of friction coefficient with increasing temperature is put into contact condition, finally, the evolutions of the temperature fields of disc and pad are obtained. Compare to the simulation result and experimental result, it shows that the contact model with dynamic friction coefficient is better fit into the actual braking condition.
