In order to reduce the sound emissivity in use, the position of the actual contact point between the wheel and the track was measured, and the mass distribution on the cross-section of the wheel rim and the wheel core was adjusted so that the contact point and the cross-section of the wheel rim were The center of inertia and the center of inertia of the wheel core section are located on the same line perpendicular to the wheel axis, and the profile of the wheel section is adjusted so that the above-mentioned junction point is the vibration node of the axial vibration mode of the wheel rim. The present invention is particularly suitable for the wheels of high-speed trains.
