摘　　要：通过对整车在转弯工况下进行受力分析并建立考虑轮荷转移的简化二自由度操纵稳定性模型,分析了车辆静态前、后轮前束值对操纵稳定性中不足转向度的影响机理,采用ADAMS仿真软件量化前束值对稳态及瞬态性能指标的影响。最后,对分析结果进行了试验验证,并对前、后轮前束值的影响敏感度进行量化分析和机理解释。Based on the analysis of the forces acting on the vehicle in turning conditions and the establishment of a simplified 2 DOF handling stability model considering wheel load transfer,the mechanism of the influence of front and rear toe-in values on the handling stability of the vehicle is analyzed in static condition.ADAMS simulation is used to quantify the influence of toe-in value on the steady-state and transient performance.Finally,the analysis results are tested and verified,and the influence sensitivity of front and rear wheel toe-in value is analyzed quantitatively and the mechanism is explained.
