摘要
根据风压对汽车行驶稳定性的分析,提出风压影响下陡坡接小半径汽车安全行驶模型,并根据车辆在风压影响下的实际运行速度进行选用技术指标。并将结论应用到工程实例中,利用MATLAB进行仿真绘制出"坡长、坡度与速度"、"速度与平曲线半径"的关系图,以供设计者选取技术指标提供依据。
According to the stability analysis of the driving vehicle under wind pressure,forward the vehicle running safety model of steep slope followed by curve with small radius under the influence of wind pressure,and selected the technical parameters according to the vehicle actual running speed under the influence of wind pressure.And the conclusion is applied to a engineering example,using MATLAB simulation to draw the relationship diagram of＂slope length、slope gradient and speed＂,and＂speed and horizontal radius＂.and to provide the basis for selecting technical indicators for the designer.
