摘　　要：以子午线轮胎385/65R22.5为研究对象,借助ABAQUS软件模拟其稳态自由滚动工况,并计算其滚动阻力,数值计算与试验值间具有较好的一致性.在此基础上,利用正交试验对轮胎的带束层结构进行优化设计,得到优化后的参数配置;对比分析了轮胎受载后的胎体变形及其滚动一周不同部位的能量损失.结果表明:合理调整带束层宽度有利于控制胎体整体形变;带束层帘线角度的改变对胎面与带束层的受力分配起主要作用;合理改变带束层宽度和帘线角度可提升轮胎滚动阻力性能.The radial tire 385/65R22.5was chosen as the research object and the free rolling state of the tire was simulated by ABAQUS,meanwhile,the rolling resistance was calculated.The numerical simulation data show good accordance with the experimental data.By using the orthogonal test method,the numerical simulation was planed,and the optimized parameter alignments were achieved.The deformed tire contour and power dissipation of different parts in a rolling cycle were analyzed.The results show that the change of belt width is beneficial to control tire deformation.The change of belt angel dominates the power distribution in tire tread and belt layer.Changing belt width and angle with proper method will enhance tire rolling resistance performance.
