ABSTRACT

In this paper, based on the dynamic mesh technology in computational fluid dynamics (CFD), the transient simulation of the curve crossing process is carried out, and the flow field distribution around the vehicle model and the change trend of lateral force and resistance are obtained. The research shows that the flow field, pressure field and velocity field around the body change with the relative position during the curve passing process. By changing the spacing, the change of the force in the process of vehicle crossing is more significantly observed, that is, with the decrease of the spacing, the change of lateral force and resistance is more unstable, which affects the safety and stability of the vehicle, makes the vehicle deviate from the original path and even causes serious accidents such as yaw and rollover.
