摘　　要：为提高微型汽车在横风作用下的驾驶安全性,文章利用ANSYS Fluent软件模拟了0°至90°风向下的风洞实验,获取和分析了不同驾驶速度、风向和风速等对车辆稳定性的影响。基于以上研究设计了一款微型汽车横风风扰响应系统,可实现车辆环境智能判定与驾驶员自动警示。该系统可提升微型汽车在复杂风环境下的安全性,拓宽其应用场景,对微型汽车的研究与应用有重要价值。In order to improve the driving safety of microcars under crosswinds,this study simulate wind tunnel experiments under 0°to 90°wind direction using ANSYS Fluent software to obtain and analyse the effects of different driving speeds,wind directions and wind speeds on vehicle stability.Based on the above research,a micro-vehicle crosswind disturbance response system is designed to realise intelligent determination of vehicle environment and automatic driver warning.This system can enhance the safety of micro-vehicles in complex wind environments and broaden their application scenarios,which is of great value to the research and application of micro-vehicles.
