This study examines the influence of dynamic stiffness in the contact region on disk brake squeal. The frequency of squeal becomes higher as the thrust pressure grows larger. We think the cause of this phenomenon is that the stiffness of the pad depends on thrust pressure, because the vibration characteristics of the disk and the caliper are not change by thrust pressure. Therefore, we measure the contact stiffness of the pad. The results show that the stiffness of the pad has pressure dependency. To clarify the influence of the pad stiffness on squeal, we analyze the disk-pad-caliper system as the surface contact analysis model, which combines the disk with the pad-caliper by distributed springs.
