| 中文摘要: |
| 为探究轮胎振动噪声与接地性态参数之间的关系,以TBR轮胎275/70R22.5为研究对象,在不改变轮胎外轮廓的条件下,通过仿真分析获得不同带束层结构设计下的轮胎振动噪声与接地性态参数之间关系。本研究依据轮胎实际结构建立仿真模型,通过接地试验及模态试验验证了仿真模型的有效性,并利用Abaqus获得轮胎接地性态参数,利用LMS Virtual.Lab 获得轮胎振动噪声数值。研究结果表明,适度增加轮胎-路面接触面积有利于降低轮胎振动噪声,轮胎-路面接触压力增加则会导致振动噪声升高,轮胎-路面接触压力偏度值的变化将会引起振动噪声剧烈波动,径向刚度增加将会导致振动噪声升高,硬度系数较小时振动噪声相对较小。研究结果为利用轮胎接地性态参数优化轮胎结构降低轮胎振动噪声提供了一定的理论指导。 |

| To study the relationship between grounding parameters and the vibration noise, taking the TBR tire 275/70R22.5 as the research object. The relationship between tire grounding parameters and vibration noise values of the different belt structures are obtained by simulated without changing the tire contour. In this study, simulation models were built based on the actual tire structure, and the validity of the simulation model was verified by tire grounding test and modal test. To study the relationship between the vibration noise and the grounding parameters of the tire ,the grounding parameters were obtained by Abaqus, and the vibration noise values were obtained by using the LMS Virtual. Lab. The results show that a moderate increase of the contact area will be beneficial to reducing the vibration noise. The increase of the contact pressure will lead to the increase of vibration noise. The change of the contact pressure bias will cause the drastic changes of the vibration noise, and the increase of radial stiffness will lead to the increase of the vibration noise. The vibration noise is relatively small when the hardness coefficient is smaller. The research results provide a theoretical guidance for optimizing tire structure and reducing tire vibration noise by using grounding parameters. |
