Techniques for Determining the Thermal Characteristics of Brake Drums and Discs 710589
Heat storage, heat dissipation, and cooling coefficients are defined; and equations, based on theory and practice, are developed with which values of the coefficients can be determined. Vehicle tests required are described. Use of the coefficients in predicting drum or disc temperatures is demonstrated, using coefficient values obtained in vehicle tests. Use of the cooling coefficient for simulating brake cooling on a brake dynamometer is demonstrated.
