摘要

This paper presents a literature review of vehicle aerodynamics research on the impact of crosswinds on vehicle stability and the optimization of aerodynamic efficiency. Through an analysis of experimental wind tunnel tests, Computational Fluid Dynamic simulations (CFD), and field studies from the literature, the paper examines key destabilizing factors for vehicles, including changes in aerodynamic forces and moments as functions of wind direction, angle, and intensity, as well as the influence of unsteady airflow and vortex formation. Special attention is given to methods for estimating critical wind velocity that causes vehicle rollover, side slip, or rotation. The study emphasizes the solutions, for mitigation of the effects of crosswinds, enhancing both safety and efficiency. Challenges in existing approaches, such as limitations in turbulence simulation, are highlighted, along with opportunities for further development within the framework of sustainable transportation. The paper identifies future research directions, including advanced models for predicting vehicle behavior, optimization of infrastructure solutions, and integration of sustainable technologies, aimed at enabling the creation of safer traffic systems.
