This work proposes a novel vehicle model for effectively scanning bridge frequencies, in which wheel size and unsprung mass are incorporated. With the advanced two-mass vehicle model, it is recognized that the moving path of the wheel is the envelope of road surface roughness. Furthermore, it is shown that the proposed vehicle model is able to scan bridge frequencies up to the fifth frequency with the desired accuracy even under high class of road surface roughness in the presence of vehicle damping, whereas the traditional two-mass vehicle model can identify no more than the first two bridge frequencies in the absence of vehicle damping.
