Abstract

Abstract:

An aerodynamics and system dynamics-based unidirectional coupling numerical model for a van truck on the sea-crossing bridge is established and verified by wind tunnel test. Then a simulation is conducted to study the high-speed aerodynamic stability of a truck on the bridge under the action of step gust and comparatively analyze the wind-resistance performance of the wind barrier with different types and structural parameters and its effects on the aerodynamic stability of vehicle. Finally， a quantified evaluation method for the wind-induced diving safety and the wind resistance design of bridges is put forward.

Key words: van truck, crosswind stability, unidirectional coupling method, wind?induced driving safety, wind barrier, transient response
