| 中文摘要: |
| 以接地面压力分布的无偏估计值作为衡量其均匀性的标准,采用二次线性规划法进行优化求解,并用三维有限元法对优化结果进行了验证。采用优化搜索带束角的轮胎的接地面压力分布的无偏估计值比原轮胎小,变化率达到1.08%,证明其接地面压力分布的均匀程度比原轮胎好,可改善胎面的不规则磨耗。 |
| 英文摘要: |
| The unbiased estimator of the ground-contact pressure distribution for a tire is taken as the criterion of its eveness,optimized with the sequence quadratic program (SQP)，and verified by 3D FEM.The unbiased estimator of the ground-contact pressure distribution for the tire with the optimized belt angle is smaller than that of the original tire and the change rate is about l.08%,which confirms that the ground-contact pressure distribution is more even and the irregular tread wear can be improved. |
