| description | The aerodynamic performance and dynamic response of two cars in overtaking maneuver under crosswind were investigated using a multi-car two-way coupling method. The coupling was achieved by exchanging aerodynamic forces obtained by computational fluid dynamic and vehicle dynamic responses acquired by multi-body dynamics in real time. The change rules of the aerodynamic force, moment, yaw angle, and lateral displacement of overtaking and overtaken cars were revealed on the basis of coupling computation. The coupling effect between aerodynamics and dynamics and the interplay between overtaking and overtaken cars were also illustrated. Moreover, the necessity of the two-way coupling was verified. Final results indicated that the posture of the body and the lateral space of the two vehicles are crucial to the stability of the vehicles during the overtaking maneuver, and the interaction between the aerodynamic forces and the dynamic response should be considered. |
