  • Vehicles driving on bridges under crosswind are affected simultaneously by the cornering force generated from the cornering property of tire and vibration responses of bridges, and the driver and passengers are prone to suffer the degradation of ride comfort. First, the cornering force expression of the tire is introduced into the lateral vibration equation of the wheel according to the nonlinear Dugoff tire model. A dynamic model of vehicle is established taking into account the cornering property of tire. Then, a framework for the wind-vehicle-bridge system is established by analyzing interactions among the natural wind, vehicles and bridges. Based on the framework, effects of the tire cornering property on evaluation of the ride comfort of vehicles under various influencing factors are studied. Results show that after taking the cornering property of tire into account, the ride comfort of vehicles can be improved by improving the lateral vibration status of vehicles. Under a crosswind of 25m/s and on good road surface conditions, the ride comfort indicator of the vehicle is improved by 20.6% when the cornering property of tire is considered.
