Abstract
A new PC-based hardware and software system has been developed to automate the data acquisition and analysis of brake noise and vibration. The system integrates advanced signal conditioning and software to acquire data rapidly in a consistent and objective manner that overcomes many testing problems. Once data has been acquired, a special algorithm is used to determine when brake noise or vibration occurs during a stop event and from which corner of the vehicle it originates. It also records speed, brake line pressures, temperatures on the pads, ambient temperature, and ambient relative humidity, so engineers will know under what operating conditions the brake noise events occurred. The system can be utilized both on vehicles running city traffic tests and on dynamometer applications.
