| 中文摘要: |
| 以315/70R22.5（花纹形式为ASL01）全钢载重子午线轮胎为研究对象，采用数值模拟方法，系统研究胎冠中心弧半径、胎冠总弧度高（h）、行驶面宽度（b）及2h/b等轮廓参数对轮胎性能的影响。结果表明：胎冠中心弧半径和b对轮胎摩擦功和温度场的影响较大，对轮胎滚动阻力的影响可以忽略不计；h对轮胎摩擦功的影响较大，对轮胎滚动阻力和温度场的影响相对较小；按照2h/b做轮胎花纹拓展时，滚动阻力基本不变，轮胎摩擦功和温度场变化明显。本研究涉及的轮廓参数对轮胎摩擦功影响较大，对轮胎滚动阻力影响较小。 |
| 英文摘要: |
| Taking 315/70R22.5（pattern form was ASL01） truck and bus radial tire as the research object，the effects of contour parameters such as the central arc radius of the tire crown，crown total arc height（h ），running surface width（b） and 2h /b on the comprehensive performance of the tire were systematically studied by using numerical simulation method.The results showed that the central arc radius of the tire crown and b had great influence on the friction work and temperature field of the tire，and the influence on the rolling resistance of the tire could be ignored.h had the greater influence on the friction work of the tire，and relatively small influence on the rolling resistance and temperature field of the tire.When the tread pattern was expanded at 2h /b，the rolling resistance of the tire was basically unchanged，the friction work and temperature field of the tire changed obviously.The profile parameters involved in this study had a greater impact on the friction work of the tire and a smaller impact on the rolling resistance of the tire. |
