dc.description.abstractBrake 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. A numerical modeling approach was developed to determine the dynamic contact pressure distribution and subsequently to investigate the onset of squeal in a drum brake system. The vibration characteristics were determined by a complex eigenvalue analysis. Analysis showed that changes in contact pressure distribution would change the center of pressure between the leading edge and trailing edge of the brake shoe. The results showed that instability occurred at 90, 180 and 270 degrees drum rotation. The analysis showed that the leading shoe is dominating the instability rather than the trailing shoe.en_US
