Analytical Study of Design Parameters on Cooling Performance of a Brake Disk

Convection heat transfer coefficients for surfaces of a brake disk are calculated, and effects of design parameters including dimensions and boundary conditions on temperature distributions of brake disks are investigated by using a three-dimensional finite element model. The maximum temperature occurs near the middle of the inner brake plate. The effect of the thickness of the supporting portion on the temperature distribution of brake disks is insignificant. Increasing the disk fillet radius decreases the temperature distribution of the brake.
