Abstract: The quasi static coupling method based on the CFD and CSD were used to study the tarpaulin structural strength.The complex three-dimensional flow field models around the tarpaulin were built when the fright vehicle runs through the wind area.The surface pressure distributions of the tarpaulin in different conditions were gained by CFD numerical simulation.Then numerical simulations on the tarpaulin structural strength caused by aerodynamic force were conducted when the freight vehicle covered wi... More
