PROCESSING SIGNALS FROM HIGH SPEED RAILWAY WHEELS

A pair of high speed Miproc-16 microcomputer systems has been delivered to British Rail for a real time signal processing application concerned with the acquisition of data from the wheels of a highspeed railway vehicle. The wheels of the vehicle are used as the transducers for the measurement of wheel/rail forces, and the equipment is designed to acquire this data and compensate for the complex calibration characteristics of the transducers by performing continuous scaling corrections as the wheels rotate. The processed data is output in analog form to a suitable chart recorder or other recording apparatus. An array of strain gages mounted on each of a pair of axially opposed wheels was wired to provide three analog signals proportional to vertical, longitudinal and lateral wheel/rail forces, and the system was designed to log, process, and display/record these three forces in real time for vehicle speeds up to 130 mile/h.
