摘　　要：为了更全面研究恒值阵风对多轴汽车操纵稳定性的影响,建立了汽车经过恒值阵风过程中侧向力和横摆力矩模型以及多轴汽车多轮转向二自由度模型,应用四阶龙格-库塔方法对模型进行了求解。通过改变阵风方向、阵风分布力大小、车速、阵风长度等相关参数,获得了侧向加速度、横摆角速度、质心侧偏角的响应曲线,分析了上述参数对多轴汽车操纵稳定性的影响。To study the influence of constant gusty wind on handling and stability of multi-axle automobile, the modle of lateral force and yawing moment while an automobile driving across constant gusty wind and two degree of freedom model of multi-axle automobile with multi-axle steering are established. The solution method for the model is presented by four order Runge-Kutta method. The response curves of side acceleration, yaw rates, and slip angle are obtaind by the change of the parameters such as direction of gusty wind, value of gusty wind distribution force, speed of autombile, length of gusty wind and it is analyzed that the influence of the above parameters on handling and stability of multi-axle automobile.
