Application of the Vehicle Scanning Method (VSM) on real bridges requires more precise analysis that can be provided by the closed form solution. Analytical solutions applied the previously proposed hybrid time effective method using ANSYS and MATLAB that makes possible to account for a vehicle mass, initial condition of the spring mass and damping. The effect of initial conditions and vehicle mass was studied in the following case study. The computed results were compared to experiments. The relation between the exciting forces caused by the scanning vehicle and vibration noise from other sources affecting the sprung mass seems to be decisive for a successful application of the VSM. A higher vehicle damping can reduce the adverse effects of initial vibration state of the vehicle when entering a bridge.
