| 中文摘要: |
| 研究胎肩横沟花纹对轮胎帘布角度效应引起的残余回正力矩（PRAT）的影响及肩部横沟花纹沟槽与轮胎纵向角度（θ）与PRAT的关系。结果表明，随着θ的增大，PRAT增大。根据该关系可在轮胎产品开发早期阶段即通过轮胎花纹设计满足车辆对轮胎残余回正力矩的要求。 |
| 英文摘要: |
| The effect of shoulder cross groove pattern on plysteer residual aligning torque（PRAT）and the relationship between the angle（θ）of shoulder cross groove with tire longitudinal direction and PRAT were investigated.The results showed that PRAT increased with the increase of θ.According to the relationship，the requirements of vehicle on the PRAT of tire could be met by tire pattern design in the early stage of tire product development. |
