Abstract To reduce the error value of weigh-in-motion caused by speeds, the physical model of vehicle is built, with analyzing the speeds on weighing accuracy, deducing their relationship and a compensative method of speeds. Then a weigh-in-motion dynamic model is built and simulated based on dynamic analysis of mechanical system. The result shows that the compensation effect is better and the accuracy of weigh-in-motion is improved, especially at the 8.33m/s, the maximum compensation amount reached 10% when the car weighed 20t.
