| 中文摘要: |
| 研究PPA噪声分析软件在轮胎花纹优化设计中的应用。进行初始轮胎花纹方案设计后，首先进行噪声频谱分析，然后借助PPA软件进行错位值优化和花纹角度调整，再生成花纹噪声频谱曲线，分析噪声能量分布。轮胎噪声测试结果表明，优化后轮胎噪声明显下降。 |
| 英文摘要: |
| The tire pattern design optimized by PPA noise analysis software was investigated.After initial tread pattern design，the noise spectrum was analyzed at first，and then the pattern was optimized through dislocation value and pattern angle adjustment by PPA software.The new pattern noise spectrum curve was generated and the noise energy distribution was analyzed.The test results of tire noise showed that the tire noise decreased significantly after optimization. |
