We made an apparatus consisting of a steel rod and a thin disk and compared an actual wheel squeal with the experimental one. Train squeal noise is generated in particular kinds of nodal diameter modes of axial vibration of the wheel and at these frequencies the damping coefficient has a small value. These characteristics have the same tendency as those of squeal noise generated in the fundamental experiment. We solved an autonomous nonlinear differential equation for the frictional vibration of the disk by the averaging method and investigated the effects of the damping coefficients and contact load on the stability of the solutions.
