Abstract

Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, Ahead of Print.
Wheel-rail noise is a critical environmental constraint on rail transit development, with curve squeal noise generated on small-radius curves being particularly prominent. This noise features high frequency and sound pressure levels, making it highly ...
