Abstract

See full text

Considerable damage to rails, wheels, and trucks can result from geometric anomalies in the wheelsets, rails, and truck hardware. A solution for identifying and quantifying geometric anomalies known to influence the service life of the rolling stock or the ride comfort for the case of passenger service is described. The solution comprises an optical system, which can be configured to accurately perform measurements at mainline speeds (e.g., greater than 100 mph). The optical system includes laser line projectors and imaging cameras and can utilize structured light triangulation.
