Abstract

Noise generated on existing narrow-gauge railway lines is composed of rolling noise and noise generated from traction drive unit. In recent years, adequate measures have been needed to cope with rolling noise due to speedup operations and the noise emitted from electric apparatus and traction drive unit.
This paper reports on the characteristics of vibratory noise radiated from wheels as obtained from running / bench tests of the wheels with different web shapes, and those with corrugated webs and straight standard type, all of which have been currently used.
