Full-Scale Field Experimental Investigation on the Intended Irregularity of CWR Track in Vertical Plane

The purpose of the following paper is to present author’s experimental field investigations a jointless railway track subjected generated imperfection and analysis response applied static loads. An optical measurement system, Pontos, was used for dynamic track’s deflections in 3D. allow us recommend direct application this system non-contact measurement, visualization simulated defects track, as presented by author. It stated that simulation an effect called hanging sleeper, short irregularity with initial parameters provided (a gap length irregularity), possible. proposed method, based on loaded load from locomotive wheels), allows description changing support condition. Moreover, it also proves its usefulness changes deflection stress values force transferred rail sleeper assumed shape simulating irregularities arising operated track. affects driving comfort safety travellers.
