The behaviour of brake squeal is analysed using a complex eigenvalue method with damping for grey cast iron (GCI) and two types of aluminium matrix composite considering different distributions of SiC particles in the aluminium matrix.The influence of the friction between disk brake and brake pad, and the behaviour of the logarithmic decrement and its stability are studied under high frequency range and the influence on brake squeal.The simulation results show that the relationship between friction factor and damping frequency plays a vital role in brake squeal when the bending mode exists in lateral direction.The analysis helps us to choose the appropriate material combination to suppress the brake squeal phenomenon in major engineering applications.
