摘要
本文中发展了混合拉格朗日-欧拉(MLE)方法以对重载子午线轮胎的冲击振动噪声进行仿真。结合室内近场噪声试验,建立了冲击振动噪声在轮胎滚动噪声中所占比重的分析方法。通过对3款不同花纹结构的轮胎进行冲击振动噪声和滚动噪声的对比分析,找出了轮胎冲击振动噪声在轮胎滚动噪声中所占比重与轮胎花纹主要结构参数的关系。结果表明,对于块状花纹重载子午线轮胎,冲击振动噪声是总滚动噪声的主要成分,可使用MLE方法进行噪声分析与改进。而对于混合花纹和条状花纹,冲击振动噪声所占比重较小。
In this paper,mixed Lagrange-Euler（MLE） method is extended to simulate the vibration noise of truck and bus radial（ TBR） tires. Combined with in-door near field noise tests,an analysis method of the proportion of vibration noise in the total rolling noise of tire is established. By a comparative analysis on the vibration noise and total rolling noise of three TBR tires with different tread patterns,the relationship between the proportion of vibration noise in total rolling noise and the main structural parameters of tire pattern is found. The results show that for a TBR tire with block treads,its vibration noise dominates the main components of rolling noise and can be analyzed and improved by MLE method,while for a tire with ribbed and compound treads,the proportion of vibration noise in total rolling noise is relatively small.
