| Abstract: | In this paper,the CA770 car is taken as an object of study,the influence of air strength is considered from the point of view of vehicle's structure while the vehicle turns around steadily,and the main parameters are calculated correspondingly. Based on the analysis of the aerodynamic characteristics,the simulation model of the turning process is established,several important factors which have an influence on the vehicle driving stability are investigated,and the comparatively precise mathematic model is built. It is found that with the increase of the vehicle's speed, the influence of air strength and air torque increases correspondingly while the vehicle turns around. The changing tendency of the parameters is also obtained. |
