Abstract
A new calculating method has been derived to determine, to some extent, the transient cross-wind force and wind yaw moment acting on a vehicle.
On the basis of a plate model, the steady-state aerodynamic characteristic and, to some extent, the three fluid dynamic influences of the partial flow, the vehicle side area and the pressure distribution are taken into account.
The method developed is simple in comparison to the usual calculation methods of fluid dynamics and is therefore suited for vehicle dynamic calculations, as well as for determining the wind forces and yaw moments of test drives. There is good agreement between the calculation results and the measurements [e.g.3,4] of other authors.
