Frictional vibration with bouncing of the pin sliding on the rotating disk was investigated. It has been well examined on a silicon nitride ball-ended pin and flat disk pair that the sinusoidal runout of disk face in the direction of pin axis caused easily bouncing of the pin. In the present paper, it will be shown that bouncing vibration is able to occur, even though there is no disk runout, if disk rotation shaft and pin axis are not strictly parallel, where the pin does not contact with the disk face at right angle.A computer simulation on outbreak of bouncing vibration was made using a combined model of translational and rotational vibration systems for the pin-on-disk tribosystem used. In the model the pin is movable linearly in the loading direction and simultaneously capable of swaying in the frictional direction. Miscellaneous parameters concerning the occurrence of bouncing, for example, squareness between pin axis and disk face, elastic rebound of the pin from disk surface, dependence of friction coefficient on sliding velocity and static friction, were under consideration in the simulation.
