EVALUATING COPPER ALLOY BRAKE DISCS BY THERMAL MODELING

An analytical thermal model was developed from existing production disc geometry for heavy trucks. The model employed the finite difference approach, in which the disc was subdivided into a number of small volumes. The model specifically simulated disc temperature response during 50 mph fade tests performed on a dynamometer. The thermal model was correlated with test data to verify and improve its accuracy, and then utilized to evaluate the effects of material and geometry changes. The study has demonstrated that thermal modeling is a valid and potentially valuable tool in the design optimization of brake discs. /SAE/
