带束层结构对载重子午线轮胎侧偏特性的影响 总被引:1,自引:1,他引:0
以345/85R16轻型载重子午线轮胎为研究对象分析带束层结构对载重子午线轮胎侧偏特性的影响。结果表明:带束层结构对载重子午线轮胎的侧偏特性影响十分显著,主要体现在纯侧偏条件下对侧向力(Fy)和回正力矩(Mz)以及纯侧倾条件下对Fy的影响;纯侧偏条件下,交叉带束层结构轮胎的侧偏刚度和回正刚度比零度缠绕带束层结构轮胎大得多;纯侧倾条件下零度缠绕带束层结构轮胎的侧倾刚度比交叉带束层结构轮胎大;纯侧偏和纯侧倾条件下,交叉带束层结构轮胎的翻转力矩与零度缠绕带束层结构轮胎几乎一致。 相似文献

带束层结构对高速轿车子午线轮胎印痕和制动性能的影响 总被引:5,自引:2,他引:3
利用MSC.Marc有限元软件模拟分析带束层结构对轿车子午线轮胎静态接地印痕、高速制动印痕和制动性能的影响,并将模拟结果与205/55R16 94W试制轮胎实测结果进行对比。结果表明:轮胎静态接地印痕的有限元模拟结果与实测结果接近,具有可靠指导意义;在相同的充气压力和负荷条件下,带束层宽度大的轮胎印痕短轴长度和印痕面积均大于带束层宽度小的轮胎,而印痕长轴长度较小,带束层钢丝帘线角度大的轮胎印痕短轴长度和印痕面积均大于带束层钢丝帘线角度小的轮胎,而印痕长轴长度较小,增大带束层宽度或钢丝帘线角度均能够增大轮胎印痕面积,通过改变带束层结构设计可以提高车辆安全性能;轮胎接地面积随着制动初始速度的提高而减小,导致轮胎接地压力增大,充气压力提高也会使轮胎接地面积减小,接地压力增大。 相似文献

AbstractThe purpose of the present research was to study the effect of different belt angles on the steady state rolling behaviour of a steel belted radial tyre with slip angle. To achieve this goal, a finite element model has been developed using ABAQUS computer software. The simulation started with an axisymmetric model to analyse the tyre under inflation pressure. Then a full 3D model was generated to model the tyre under static vertical load. Having obtained the tyre configuration under contact load, a steady state rolling analysis was conducted using a mixed Lagrangian/Eulerian technique. The final stage of the modelling was the inclusion of the slip angle in the model. Each set of simulations was repeated for three belt angles and the effect of the belt angle variation on the tyre structural variables, including contact pressure and area, lateral force, interlayer shear stress and total strain energy was examined. In addition, the computed value of the number of revolutions per kilometre was compared with experimentally reported data which confirms the accuracy of the present model. 相似文献

介绍11R22.5公交专用子午线轮胎的设计及其侧偏特性仿真情况。轮胎外直径和断面宽分别取1054和280mm,胎圈着合直径取571.5mm,采用低噪声RT606胎面花纹;胎体采用3+8+13×0.18+0.15HT钢丝帘线;带束层为4层结构,1#带束层采用3×0.20+6×0.35HT钢丝帘线,2#和3#带束层采用3+9+15×0.22+0.15钢丝帘线,4#带束层采用5×0.35HI钢丝帘线;采用六角形钢丝圈。有限元分析结果表明,轮胎接地形状接近椭圆,压力分布比较均匀;侧偏角(α)不超过5°时侧向力(Fy)和α呈线性关系,α在10°附近时Fy达到峰值;α为2°~4°时回正力矩(Mz)达到峰值,随着α的进一步增大Mz迅速减小;轮胎的侧偏特性受轮胎与地面间摩擦系数的影响;侧倾角对Fy影响很小,对Mz影响显著。 相似文献
