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。Research on intelligent noise reduction optimization and comprehensive noise diagnosis is the emphases of this paper
輪胎花紋結構參數智能降噪優化和噪聲綜合診斷是本課題重點。According to the academic fruit of my tutor and his graduated students on tyre pattern noise simulation analysis, the previous algorithms are perfected and testified
