Statistical Analysis of Brake Noise Matrices

This paper will survey different noise matrices used in the brake industry to evaluate brake noise performance on dynamometers. Results that show temperature dependence, temperature history, braking power as well as brake pressure and initial velocity will be presented. Statistical analysis of both dynamometer and road test cycles will be presented. The results will emphasize how different cycles cover the space of pressure, initial temperature, initial speed, and stop brake power. Recommendations for controlling the different parameters will be given.
