Abstract
This article presents transient handling analysis with a full-vehicle non-linear
multi-body dynamic model, having 102 degrees of freedom. A transient cornering manoeuvre,
with a constant steer angle and velocity has been undertaken. The effects of aerodynamic lift
and drag forces have been included in the simulation tests. The vehicle handling characteristics
with and without aerodynamic forces have been compared and various observations made. The
aerodynamic forces have been predicted by a k¿1 model solution of the Navier¿Stokes equations
for turbulent flow. The numerical predictions for the evaluation of aerodynamic lift coefficient
agrees well with the scaled-down air tunnel experimental work, using hot-wire anemometry
