Abstract

"APERFEIçOAMENTO DO BARULHO DE BANDA DE RODAGEM POR MEIO DA MODULAçãO DA FREQuêNCIA DE RESSONâNCIA DE RANHURA". Um pneu 10 possui uma pluralidade de elementos de banda de rodagem de ombro 50 definidos por ranhuras laterais 17a e 17b e por ranhuras circunferências 15. A banda de rodagem 12 do pneu 10 é declinada usando três ou mais tamanhos de pico. Cada pico possui uma ranhura lateral 17a aberta para a ranhura circunferencial adjacente 15 ou fechada para a ranhura circunferencial adjacente como uma função de uma seq³ência predeterminada de não uniformidade.
