| 中文摘要: |
| 研究半消声室内轮胎噪声测试方法。方法一用转鼓试验机直接测得轮胎噪声声压级和频谱曲线，未控制温度和湿度等条件；方法二参照国外室内轮胎噪声测试标准对测试条件进行调整；方法三对方法二再进行适当修改。研究表明室内轮胎噪声测试结果与室外滑行法噪声测试结果趋势基本一致。方法一操作简单、速度快，但易造成测试偏差；方法三操作和程序较繁琐，但测试精度高；方法二介于两者之间。 |
| 英文摘要: |
| The testing methods of tire noise in semi-anechoic chamber were studied.Method Ⅰ directly measured the sound pressure level and spectrum of tire noise by drum test machine without controlling the temperature and humidity conditions.Method Ⅱ adjusted the test conditions by referring to foreign standard of indoor tire noise testing.Method Ⅲ appropriately modified method Ⅱ further.The results showed that the test result of indoor tire noise was similar to that of coast-by test method.Method Ⅰ test was simple and rapid,but could easily lead to test bias.The operation and process of method Ⅲ were more complicated,but it possessed high test accuracy.The accuracy of method Ⅱ was between method Ⅰ and method Ⅲ. |
