The authors analyze the coupled vibrations between wheels and a rail in the horizontal direction, taking Kalker's linear creepage theorem into account as the rolling contact model. They calculate the steady-state responses of SHlNKANSEN wheels and a 60kg rail at the points of contact, and the integral estimations of the vibration velocity all over the wheels and the rail. As a result, it is found that the rail is strongly influenced by the wheel characteristics in the coupled vibration while the wheels themselves hold their individual ones. The contributions of wheels and rail to the rolling noise are also examined in the horizontal vibrations.
