Abstract:The threedimensional transient temperature field for diskbrake were simulated using software ABAQUS to study the effects of specific heat capacity and thermal conductivity on the temperature distribution of the brake material during its braking process.The results show that the temperature gradient in the axial and radial direction of friction plate can be reduced,while the transient maximum temperature on the friction surface can be increased by increasing the thermal conductivity of friction plate.The transient maximum temperature of friction surface can be reduced,while the temperature gradient in the axial and radial direction of friction plate can be increased by increasing the specific heat capacity.Compared to the thermal conductivity,the specific heat capacity has more significant effect on the maximum transient temperature of friction plate.The maximum transient temperature and the axial and radial temperature gradient can be reduced by increasing the specific heat capacity and the thermal conductivity at the same time.
