The vehicle running stability and safety on the bridge under strong crosswind has become a hot topic. Previous researchers did not fully utilize the on-site monitoring data of bridge responses. To solve wind-bridge-vehicle interaction, this paper is to solve two fundamental issues. Firstly, it presents a new scheme of Vehicle-Bridge-Interaction system by combining the FEM and Multiple Body Simulation (MBS) to be more convenient and comprehensive to analyze the system. Then regarding the limit number of measurement sensors, Perturbed Force method is used for obtaining responses of unmeasured parts and combine with the model to avoid the complicate fluid-structure interaction analysis.
