Measurement technology for a calibrating vehicle for multiple sensor weigh-in-motion system

The Dutch Ministry of Transport, Public Works and Water Management. requested an instrumented vehicle to calibrate their Multiple Sensor Weigh-In-Motion (MSWIM) system that is under development for automatic enforcement of axle loads and vehicle weights. The vehicle was planned to be built for calibration of static weigh bridges, and has been redesigned for the purpose of calibrating MSWIM systems. TNO has developed and built the measuring system and software. The first axle on the semi-trailer has been instrumented with strain gauges and accelerometers. The data is collected with a sample rate of 8 kHz. The system clock is synchronised with an accurate GPS time trigger. The same GPS time trigger is used for synchronisation with the MSWIM system. The dynamic wheel loads are calculated using data from the strain gauges and from accelerometers measuring wheel accelerations.
