Wheel load control system of a railway vehicle using noise spectrum analysis and GPS/GPRS technologies

This article describes the wheel control system of a railway vehicle. Using a GPS satellite and GPRS technologies, the proposed system adjusts air suspension depending on noise spectrum analysis from the wheel-rail contact and track characteristics. This system provides a model with effective distribution of wheel load between wheels and rails. As a result, it allows a railway vehicle to be driven in a tractive mode by the maximum adhesion force for real friction conditions and to avoid a derailment.
