Experimental Method for Driving Simulation on the Long-span Bridge Under Wind-vehiclebridge Coupling

Abstract:

In order to carry out a more detailed study of driving safety on long-span bridges, based on the wind-vehicle-bridge coupling theory, the bridge vibration effects under three wind speeds are calculated and a long span bridge driving simulation experiment scenario considering both the crosswind and the vibration was established. Twenty drivers were divided into two groups according to the driving experience, and the driving simulation experiment was conducted. The results show that in the late stage of crosswind, the lateral displacement and the yaw speed of the vehicle affected by bridge vibration are larger than those without vibration. Bridge vibration effect will have a positive warning effect and adverse interference to driver, for the driver with relatively lack of experience, crosswind and vibration combination is more detrimental to traffic safety.
