Representation of Brake Operational Characteristics Using a One Line Equation 900167

A technique has been devised whereby brake thermal characteristics may be determined by measuring brake temperature, vehicle velocity, and braking torque over a wide range of operating conditions. The relationships between these experimental parameters are then determined using statistical methods of regression analysis. With the use of computer data acquisition systems, and the relative ease with which massive amounts of data may be accumulated, mathematical relationships may be developed. These rather simple mathematical relations then can be used to indicate such complex phenomena such as heat transfer coefficients from the brake surface.
