After analyzed the basic principle of optimized noise reduction on tyre pattern , summarized three approaches to noise reduction . the first is trying to reduce size of single block or socket to reduce noise amplitude on time domain , the second is to adjust stripes sorting order and their interlace value to avoid noise - made by every single block - peak values on time domain overlayed and the last is to adjust ratio of blocks and sockets , ratio of stripe interval and stripe sorting order to avoid noise periodical distribution and abnormal high peak values in some frequency strip 论文第四章分析了轮胎花纹优化降噪的基本原理,总结出三条降噪途径:在允许范围内尽量减小单个块或槽的大小、刻刀槽软化花纹块来减小噪声时域波幅度;调整节距排列顺序、花纹条之间的错位值,使各发声单元发出的声压时域波形的同向峰值错开,避免同向峰值叠加;调整花纹块和槽比例、节距比例、节距排列顺序,尽量避免周期性分布,使轮胎所发出的噪声趋于白噪化,避免某些频段的异常高峰值。
