| 中文摘要: |
| 侧向松弛长度反映轮胎的瞬态特性，采用状态空间法，基于二自由度线性车辆动力学模型，建立添加侧向松弛长度的车辆模型，研究轮胎瞬态特性对车辆动力学特性的影响。结果表明：轮胎的瞬态响应不会对车辆稳态响应产生影响；添加侧向松弛长度的影响后，车辆响应变慢，横摆超调量增大；侧偏刚度变化对横摆角速度峰值、横摆角速度延迟时间和横摆角速度响应时间的影响更大，侧向松弛长度变化对超调量的影响更大。 |
| 英文摘要: |
| The lateral relaxation length reflects the transient characteristics of tire.By using state space method and based on the two-degree-of-freedom linear vehicle dynamics model，a vehicle model with the lateral relaxation length was established to study the influence of the tire transient characteristics on the vehicle dynamic characteristics.The results showed that the transient response of the tire would not affect the steady-state response of the vehicle.After adding the influence of the lateral relaxation length，the vehicle response slowed down and the yaw overshoot increased.The change in cornering stiffness had a greater impact on the peak value of the yaw rate，the delay time of the yaw rate and the response time of the yaw rate，while the change in the lateral relaxation length had a greater impact on the overshoot. |
