Abstract

This paper analyzes the correlation between the maximum safe driving speed of vehicles on the main body of the whole bridge and the typhoon series based on different wind directions. Firstly, the joint probability density model of typhoon wind level and wind direction is constructed. Secondly, the mathematical model for safe driving of vehicles is constructed based on the aerodynamic six component force. The circular curve, up and down ramp and combined alignment are selected as the representative road routes of bridge, tunnel and castle. The 1:1 light vehicle is set up with different wind speed levels for fluid simulation. Finally, it is concluded that there is a negative correlation between the maximum safe driving speed range of vehicles on the main body of the whole bridge and the typhoon series of 1-16.
