The rolling noise arises from the interaction of the vibration characteristics between wheels and rail through contact points. The authors treated the vibration of a rail in the horizontal and vertical directions in the previous papers. In this report, the axial vibration of a rotating wheel at the circumference of which shear force and spin moment from Kalker's linear creep theory act simultaneously is formulated in order to consider the coupled vibration between wheels and rail in the horizontal direction. It is shown that the response of the steady-state vibration is obtained by solving the simultaneous algebraic equations with respect to the contact forces. As an inspection of the present analytical method, the theoretical impedance characteristics of a stationary wheel suspended with springs at a point on the outer circumference are compared with the experimental ones.
