Analysis of Vehicle Stability in Crosswinds

Recently, the improvement of the straight line stability has been required in mini-sized vehicles to be equivalent to that of compact cars, particularly the crosswinds stability at high speed. In this study, the new numerical simulation method has been developed, for improving efficiency, by combining the CFD (Computational Fluid Dynamics) analysis with the numerical analysis of vehicle dynamics. The vehicle behavior in the crosswinds is computed using the full-vehicle dynamic simulation model included the 6 components of aerodynamic force of the gravity center.
