Influence of Track Defects on the Track-Loads and Confidence Interval of a Track Recording Car
Author: Konstantinos S. Giannakos
Abstract: The Railway track, is simulated as a beam on elastic foundation with damping. The motion of a vehicle is simulated by the 2nd order differential equation of motion; the input to the system “vehicle-rail” is the form of the Track Geometry which “acts” as a “signal”. The defects with short and long wavelength influence the value of the dynamic component of the acting loads on the railway track and they are recorded in the frame of the Quality Control of the Railway Track, which presents a determined Confidence Interval depending on its “measurement-base”.
