Abstract:
The precision of weightinmotion (WIM) of vehicles is influenced by lowfrequency dynamic load from vibration of vehicles. A new method based on combination of the empirical mode decomposition (EMD) method with nonlinear curve fitting method is proposed for weightinmotion of vehicles when the sampling data sequence is too short to get two extreme points as the vehicles passing through the weighing platform with highspeed. The simulations and onsite experiments are carried out to reduce lowfrequency dynamic load. The results illustrate that this method can effectively reduce the impact of the dynamic lowfrequency load on the accuracy of weighing, and the maximum error is less than 5% when the vehicle velocity is lower than 40 km/h. 1 tab, 2 figs, 7 refs.
