Abstract:

In order to solve the problem of highway traffic safety in the mountainous area, vehicle transient aerodynamic feature and its laws in bridge and tunnel connecting segment affected by the wind environment are studied. With the help of Carsim software, the vehicle model and the road model are built to simulate the feature of the vehicle and road in bridge and tunnel connecting segment. The measured varying wind speed of Xihan Expressway is input to simulate the average wind and fluctuating wind of the natural wind load, and the influence of wind angle on the vehicles is researched. Firstly, after simulation, the parameters, such as vehicle longitudinal speed, lateral acceleration, aerodynamic force(drag force, side force and lift force) and aerodynamic slip angle are analyzed. Then, the influences of the vehicle aerodynamic forces of different vehicle speeds, wind speeds and wind directions on the driving stability are analyzed. Finally, the critical vehicle speed and critical wind speed of safe and stable driving in the side wind environment are investigated. Research results show that, when the vehicle speed is increased from 60 km/h to 80 km/h, the drag force, side force and lift force are increased by 160%, 53% and 89% respectively. Under the snow and ice surface with wind speed of 80km/h, a large offset of more than one meter occurs. When the maximum wind speed of Xihan Expressway was 31.5 m/s (about 113 km/h), the vehicle will obviously overturn and it will be a risk to driving safety.
