轮胎花纹噪声仿真频谱评判法

Estimation of Tread Pattern Noise by Simulation Spectrometry

提出一种轮胎噪声主观评价强弱权重函数Ｎ＝ｎ（ｆ，ＰＳＰＬ）与轮胎噪声频谱能量均衡函数ζ相结合的综合评价方法。仿真实验验证，用此方法评价轮胎花纹的噪声，结果与国外先进方法的结论一致。

A comprehensive estimating method of tread pattern noise,in which the subjective estimated result,the weighted function N was combined with the spectrometric energy,equalized function ζ ,was proposed.It was shown by the simulation test that the results from the said estimating method of tread pattern noise were in accordance with those from the sophisticated methods in advanced countries.
