摘要
通过研究国外的噪声性能指标标准线 ,制定出花纹噪声频谱线、频域声能量均衡线、时域声中心能量分布均衡线和声强度图相结合的“三线一图”轮胎花纹低噪声客观评判标准 ,并将其与含有响度、尖锐度、起伏度和烦恼度 4个评判因子的主观评判方法相结合 ,提出一种轮胎花纹噪声的综合评判方法。该方法能合理地筛选出最优或较优的方案样本投入生产 ,从而可以大大缩短轮胎开发周期和节约开发费用 ,实际应用效果良好。
An objective judgement of tire tread patterns noise consisting of the noise frequency curve,the frequency field sound energy equilibrium curve,the time field central sound energy distribution equilibrium curve and the sound density pattern is combined with an subjective judgement including the sound pressure level,the sharpness,the fluctuation and the vexation to form a comprehensive judgement of tire tread patterns noise.It is found that the most optimal or more optimal tread patterns can be screen out by using the said comprehensive judgement,thus the development period and expenditure of tire are significantly reduced.
