Abstract

This study presents a modern concept of the amplifier that can be used in the vehicle–bridge interaction system to enhance the performance of vehicle scanning method by using the semi-analytical approach. Based on the sophisticated vehicle model, the vibration amplifier is introduced to the pinnacle of the vehicle model to compose an amplifier–vehicle–bridge (AVB) system. With this additional degree of freedom, the semi-analytical solutions have shown that the vehicular responses are amplified in comparison with those obtained by the vehicle–bridge interaction system without an amplifier. The proposed AVB system can be served as reference solutions when more parameters or complex situations are to be investigated in an AVB system using a simply supported bridge.
