An Alternative Rail Pad Tester for Measuring Dynamic Properties of Rail Pads Under Large Preloads

Abstract: Kaewunruen, S. and Remennikov, A. M. (2008). An alternative rail pad tester for measuring dynamic properties of rail pads under large preloads. Experimental mechanics, 48 55-64. Abstract One of the main components in ballasted railway track systems is the rail pad. It is installed between the rail and the sleeper to attenuate wheel/rail interaction loads, preventing the underlying railway sleepers from excessive stress waves. Generally, the dynamic design of tracks relies on the available data, which are mostl… Show more
