In order to analyze the dynamic behavior of the vehicle subjected to crosswind, we constructed a dynamic analysis model which was developed based on the static analysis model, and examined the effect of the frequency of the crosswind on the dynamic behavior of the vehicle. Further, in order to verify the validity of the dynamic simulation program prepared by using the dynamic analysis model, we conducted a full scale experiment applying lateral force to the vehicle dynamically. As a result, it has been verified that the dynamic simulation program is valid for evaluating the wheel load variation of the vehicle which is subjected to crosswind. Consequently, the effect of the frequency of crosswind on the behavior of the vehicle has been clarified, the critical wind speed of overturning has been evaluated more precisely, and also the difference between the static analysis and the dynamic analysis has been evaluated quantitatively.
