| 中文摘要: |
| 基于非线性有限元分析软件Abaqus，采用流-固耦合方法对轮胎噪声进行数值模拟。结果表明：轮胎近场噪声试验与仿真结果都具有明显的指向性，轮胎接地前后端的声压级最大，且接地后端的声压级大于接地前端，90°测点的声压级最小；轮胎近场噪声的声压级在中高频段的衰减速度与花纹横沟宽度呈负相关；90°测点频谱特性的仿真结果与试验结果非常接近，误差范围为4～12 Hz；节距噪声基本频率与花纹横沟宽度无关。 |

| Based on the nonlinear finite element analysis software Abaqus，the noise of tire was simulated by the fluid-solid coupling method.The results showed that the test and simulation results of tire near-field noise had obvious directivity.The sound pressure level at the rear end of the tire before grounding was maximum，and the sound pressure level at the rear end of the tire was higher than that at the front end of the tire，and the sound pressure level at the 90° measuring point was minimum.There was a negative correlation between the attenuation speed of the sound pressure level of the tire near-field noise and the width of the tread groove in the middle and high frequency band.The simulation results of the spectrum characteristics of 90° measuring points were very close to the test results and the error range was 4～12 Hz.The basic frequency of pitch noise was independent of the width of cross groove. |
