| Abstract: | Dynamic tire force is the important factor that influences the weighing accuracy of moving vehicles.A quarter-car model was used to deduce the vehicle transfer function,and dynamic tire force equation was built based on the road profile displacement spectral density and the deduced vehicle transfer function.By digital simulation,the amplitude and frequency characteristics of dynamic tire force were analyzed,and the influences of road roughness,vehicle velocity,vehicle load,tire stiffness and suspension stif... |
