Abstract: A system for on-board measurement and modelling of dynamic wheel/rail loads employs an accelerometer in addition to force sensors at the axle box of the test vehicle. The force sensors accurately measure dynamic wheel/rail force at low frequencies. The force transfer function at higher frequencies is calculated as a predetermined function of both the accelerometer and force sensor data. For example, this can be calculated by means of a predetermined compensation force transfer function in terms of both the force and acceleration readings.

Abstract: A wheel load sensor system has two independent shear load sensing circuits, a wide circuit and a narrow circuit, that are fixed along the neutral axis of the rail in the span between ties. The responses of both circuits are initially calibrated by applying known loads at predetermined points along the span to generate sensitivity curves from each circuit. This configuration allows the present system to account for the longitudinal position of the load applied within the crib based on the ratio of the response signals from the two circuits. This ratio can be used to accurately determine the location of the wheel load within the crib. The magnitude of the load can then be calculated from the sensitive curve for either circuit.
