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
論文第四章分析了輪胎花紋優化降噪的基本原理，總結出三條降噪途徑：在允許范圍內盡量減小單個塊或槽的大小、刻刀槽軟化花紋塊來減小噪聲時域波幅度；調整節距排列順序、花紋條之間的錯位值，使各發聲單元發出的聲壓時域波形的同向峰值錯開，避免同向峰值疊加；調整花紋塊和槽比例、節距比例、節距排列順序，盡量避免周期性分佈，使輪胎所發出的噪聲趨于白噪化，避免某些頻段的異常高峰值。 -
( 1 ) analyze the mechanism of the friction between the tyre and pavement and the factors which affect the friction ; the friction between tyre and pavement involves four aspects : the molecule force, the adhesion between tyre and pavement, the elastic distortion of rubber on the tyre surface and the tiny cutting of the little - size protruding on pavement
鄭州大學碩士學位論文摘要一輪胎與路面間的摩擦力主要有四個方面：輪胎與路面間的分子力作用：輪胎與路面間的粘著作用；胎面橡膠的彈性變形；路面上小尺寸微凸體的微切削作用。
