| 中文摘要: |
| 研究了一种预测轮胎滚动振动噪声的新方法，提出用混合的拉格朗日-欧拉方法来解决瞬时变动的拉格朗日网格上的振动信息向欧拉网格上映射的数据转化问题。首先进行带花纹轮胎的瞬态滚动计算，然后提取外表面的节点加速度，采用混合的拉格朗日-欧拉方法将节点加速度变换到欧拉网格上，将欧拉网格上的振动加速度导入LMS Virtual LAB声学软件进行振动噪声的仿真计算。仿真计算结果与试验结果的对比证明了仿真方法的合理性。 |

| In this study，a new method to predict the vibrational noise of rolling tire was investigated.The data transformation from the vibration information of transient variation in Lagrange mesh into the data in stable Eulerian mesh was achieved by using mixed Lagrangian-Eulerian method.specifically，at first，the rolling state of a patterned tire was simulated and the nodal vibrational accelerations of outer surface were extracted.The vibrational accelerations were transferred to the nodes of Eulerian mesh using the mixed Lagrangian-Eulerian method，which were then input into the acoustical simulation software LMS Virtual LAB to simulate the vibrational noise.The comparison between the simulation result and the test result showed that this method was reliable and effective. |
