| 中文摘要: |
| 基于二自由度线性车辆模型，研究轮胎侧偏刚度、横摆角速度波动固有频率（f0）对车辆操纵性能的影响，计算车辆对前轮转角阶跃输入时瞬态响应的客观评价指标，并利用线性回归方法分析轮胎侧偏刚度和f0与实车主观性能评价结果的相关性，结果表明，与侧偏刚度相比，f0与实车转向响应评分具有更强的正相关性。 |
| 英文摘要: |
| The influence of the cornering stiffness and yaw velocity fluctuation natural frequency（f0）on vehicle handling performance was studied.Based on the two-degree of freedom linear vehicle model，the f0，which was an objective evaluation parameter to characterize the quality of the transient response of vehicles to the front wheel step input，was calculated.The linear regression method was used to analyze the correlation between cornering stiffness，f0 and subjective evaluation score of vehicle performance.The results showed that，compared with the cornering stiffness，f0 had a stronger positive correlation with the vehicle steering response score. |
