摘　　要：为了揭示弹性轮胎的侧偏特性对车辆操纵稳定性的本质影响,以广义汽车转向稳态响应模型为基础,对安装不同特性车轮的车辆分别进行了转向动力学分析,并通过运动特性参数的差异性对比,确定了有别于传统二自由度模型的汽车稳态响应特性的新的判别依据,然后通过实例分析,验证了新的稳态响应特性判别依据的可行性和优越性.Based on the generalized steering steady response model,the steering dynamic analysis of the automobile with different kinds of wheels was performed,and the differences of movement characteristic parameters were compared.Then a new discriminant rule of steady steering characteristics based on the new model,which is different from the traditional two-degree-of-freedom model,was determined.The calculate results for two different cars showed that the new discriminant rule of steady steering characteristics was feasible and superior.
