摘　　要：基于整车动力学理论,构建了整车虚拟仿真模型。采用某车型双移线试验数据,对该模型进行了验证与调整。应用该校正模型,研究汽车质量在纵向的位置分布特性对汽车操稳性能—包括转向盘转角与横摆角速度之间的滞后时间、转向盘角速度和汽车质心侧偏角等关键参数的影响。Based on vehicle dynamics theory, a full vehicle simulation model is built. The full vehicle simulation model is verified and rectified by the double lane-change experimental data. Then, the model is used to study on the effects of the vehicle mass distribution in the longitudinal direction on the key parameters of vehicle handling performance, including the delay time between steering wheel angle and yaw rate, the angular velocity of steering wheel and side slip angel as well.

关 键 词：操纵稳定性 双移线试验 滞后时间 侧偏角
