Abstract

The dynamic meshing technology in computational fluid dynamics (CFD) is used to simulate the transient overtaking process of right turning vehicles and straight running vehicles. The characteristic of flow field around the vehicle model and the variation trend of lateral force and yawing moment are obtained. The research shows that when the speed of the straight vehicle increases, its lateral force and the yawing moment of both vehicles increase, while the lateral force of the right turning vehicle increases first and then decreases; The turning radius of the right turning vehicle increases, the lateral force of the two vehicles and the yawing moment of the straight vehicle decrease linearly, and the yawing moment of the right turning vehicle increases linearly.
