Abstract:The three-dimensional transient temperature field for disc brake were simulated using software COMSOL Multiphysics,the situation of temperature distribution for friction pairs device in the braking process and the effect of material thermal parameters on its temperature field were investigated.The results showed that at the high-temperature moment of the braking process of the disc brake,the high temperature place was located on the area of sliding out with the friction plate along the disk rotates direction;the surface temperature of brake disc decreased from the high temperature zone along the direction of the brake disc rotation;the surface temperature of friction plate decreased along the opposite direction of the brake disc rotation;the maximum radial temperature of the brake disc and friction plate in the braking process was located on the central part of the friction zone,the temperature of the outside radius and inside radius was lower,the temperature of the axial direction decreased from the friction surface layer to the inner layer direction;it can reduce the maximum temperature value of friction deputy surface by increasing any thermal parameter of the brake or friction plate,but compared to the friction plate,the effect of thermal conductivity,specific heat capacity and density of brake disc was much greater than the effect of friction plate’s on the temperature of the friction deputy,the research content can provide a reference for the structural design and material selection of brake.
