In research on using vehicles to extract bridge frequencies, single degree-of-freedom vehicles and two-dimensional bridges cannot fully simulate vehicle-bridge interaction and bridge frequency extraction. Therefore, a method of using two-axle vehicles to extract the vertical and flexural-torsional frequencies of three-dimensional (3D) bridges is proposed. First, the feasibility of this method is theoretically verified by analytical methods. Subsequently, a signal enhancement approach, combining successive variational mode decomposition (SVMD) and a designed window function, is proposed. SVMD p...
