Abstract

An axle weighing system is a system that measures each axle weight of in-motion vehicles while they pass though on the weighbridge. In the weighing, signal processing technique is the key to achieve the precise measurement since the output signal from the weighbridge is contaminated with the noise due to the vibration of the vehicle in motion. In our previous paper, we proposed a new signal processing method using normal equations to estimate the vibration parameters. In the present paper, we examined the relation between the velocities of in-motion vehicles and the estimated values obtained with the new method, through a consideration on the computer simulation with the output signal generated by using the linear models of vehicles. As a result, it was clarified that precise estimation is possible when the velocity of a vehicle is approximately less than 15 km/h.
