COPPER DISC BRAKES ON THE ADVANCED CONCEPT TRAIN I

The friction brake system components described in the paper were developed on behalf of the United States Department of Transportation for the Advanced Concept Train I (ACT I), a 220-passenger rapid transit rail vehicle. The choice of chrome copper as disc material and disc-associated friction lining was made to meet severe friction-brakes-only operating mode and utilizes the high friction coefficient and diffusivity of chrome copper. Results from dynamometer tests and from a limited program of rail trials corresponded well with predictions contained in the thermal analysis. Braking rates were maintained and occasionally exceeded during simulated round trip tests at disc surface temperatures to 850 K.
