Analysis Of The Effect Of Roundness On Drum Brake Squeal Using The Finite Element Method

Kebisingan brek adalah dikaitkan dengan ketidakstabilan dinamik bagi pasangan mod komponen-komponen individu sesuatu sistem brek. Ketika proses menekan brek dilakukan, taburan tekanan sentuhan di sepanjang antaramuka bahan geseran didapati tidak seragam. Di samping itu, kesan kebulatan gelendong brek menunjukkan hubungan yang kuat terhadap taburan tekanan tersebut. Kesan kebulatan gelendong brek terhadap keupayaan kebisingan dikaji dalam penyelidikan ini. Brake squeal is associated with the dynamic instability of a coupled mode of individual components of brake system. During the braking process, the contact pressure along the friction material interface is not uniformly distributed. Furthermore the effect of roundness on drum brake shows the strong relation towards contact pressure distribution. In this research, the effect of roundness on drum brake towards squeal propensity was studied
