(2) The result of two scenarios of a vehicle operating through a simply supported beambridge at velocity of 20m/s, 40 m/s, 60 m/s and 80 m/s show that for moving point, theauto-PSD coincides with the target model especially within the natural frequency rangeof high-speed railway vehicles; the longitudinal cross-correlation and auto-PSD of staticpoints are in agreement with the target functions.
