The effects of normal force variation due to disk inclination in friction-induced vibration are investigated. The investigations on friction-induced vibration should be done on the basis of experiment since complicate phenomena occur depending on experimental conditions. In this study, a friction experiment is performed using an experimental apparatus of pin-on-disk type. The experimental results show that friction coefficient is a function of relative velocity, not of normal force, and also show that squeal of severe vibration occurs due to the normal force variation which is resulted from the inclination of the disk. For the justification of the experimental results, a two-degree of freedom model of friction-induced vibration is suggested and calculated the response numerically.
