Abstract
An axle weighing system is equipment that measures each axle weight of an in-motion vehicle. A dynamic model of the weighbridge for the equipment has been made in order to elucidate the cause of inaccurate values measured by the equipment. Since the signal from the weighbridge reflects the event of the passage of tires, the model is eventually expressed by a set of linear variable-coefficient ordinary differential equations. Simulated signals generated using the model enables us to introduce and evaluate some useful methods to accurately measure axle weights of in-motion vehicles driven at high velocity.
