| 中文摘要: |
| 通过测试轮胎侧偏刚度K、转向力因数C、回正力矩系数A、负荷灵敏度H、负荷转移灵敏度G等动力学参数，并利用UNITIRE模型进行参数辨识，分析相同轮廓195/65R15轿车子午线轮胎结构与动力学参数的关系。模拟分析结果表明，采用高三角胶、两层胎体帘布层一高一低反包结构的方案B轮胎的胎侧刚度最大，K最大，C最大，H最大，G较小，可使车辆转向反映灵敏，同时保持良好的操纵稳定性和行驶稳定性；采用胎体帘布层高反包结构且胎体帘布层复合材料模量略高的方案C和D轮胎的下胎侧刚度大，A大，能更好地保证驾驶安全性；采用胎体帘布层低反包结构且胎体帘布层复合材料模量略高的方案A轮胎的K，C，A和G最小，综合性能差。 |

| The correlation between structure and cornering properties for 195/65R15 PCR tire with same profile was investigated.Tire dynamics parameters were tested and modeled by UNITRIE，such as cornering stiffness K，cornering force coefficient C，self-aligning moment coefficient A，load sensitivity H and load transfer sensitivity G.The simulation results showed that，design B with the structure of high bead filler and double carcass plies(one high and one low turn-up height) had maximum values of sidewall stiffness，K，C and H，and smaller G value.This design endowed sensitive response to vehicle steering，and better vehicle handling and stability.Both design C and design D with high turn-up height carcass ply structure and higher modulus for carcass plies had high value of stiffness in the lower sidewall and maximum value of A，and endowed better vehicle handling safety.Design A with low turn-up height carcass ply structure and higher modulus for carcass plies had minimum values of K，C，A and G，and endowed tire worse general performance. |
