Abstract

In this study, a three-mass vehicle model enhanced by an adjustable amplifier is proposed to enhance the resolution of frequency identification in the vehicle scanning method. The analytical formulation of the proposed vehicle-bridge system is derived. It is found that the visibility of fundamental and higher bridge frequencies can be achieved through the tuned mass damper effect of the amplifier in its spectrum, while such an effect has almost no influence on the resolution of frequency identification in the vertical and rotational vehicular spectra. The pitching effect has shown that the rotational vehicle spectrum has better resolution than the amplifier spectrum without tuning amplifier frequency.
