Abstract
The vibration analyses in which the head of the wheels is harmonically excited in radial direction were carried out by using FEM for the wheels of Straight web. TGV-type web and Wavy web with four kinds of circumferential wave number, and then by taking those vibration responses as boundary conditions the acoustic analyses using BEM were conducted to obtain the acoustic radiation power. And by random vibration analyses considering the rail surface roughness, the mean square velocities of rail at the contact point between rail and wheel were calculated. From the above results, the sound radiation powers of various-type wheels were examined in order to clarify the influence of wheel configurations upon the rolling noise of the railway wheel / rail system and to get the fundamental knowledge towards the optimal design of the configurations of the wheels with wavy web.
