| Abstract | ||
| Super long-span bridges provide people with great convenience, but they also bring traffic safety problems caused by strong wind owing to their high decks. In this paper, the large eddy simulation together with dynamic mesh technology in computational fluid dynamics (CFD) is used to explore the mechanism of a moving vehicle\'s transient aerodynamic force in crosswind, the regularity and mechanism of the vehicle | ||
