SPECIAL PROBLEMS AFFECTING THE RAILWAY TRACK IN HIGH-SPEED RUNNING (RIGIDITY, DAMPING EFFECT, TRACK DEFORMATION)

BESONDERE PROBLEME DES OBERBAUS BEI HOHEN FAHRGESCHWINDIGKEITEN (STEIFIGKEIT, DAEMPFUNG, GLEISLAGEVERSCHLECHTERUNG)

Track displacement under the effects of high speed and the study of the mechanisms involved is the subject of new investigations. The development of suitable vehicle/track models plays an important part in this. Track rigidity and damping effect are determined under test-rig and practical operating conditions. From this the visco-elastic behaviour of the ballast bed is determined, i.e., the time-dependent deformation. Ballasted tracks generally have a greater damping effect than non-ballasted tracks, so that oscillations at defective places die away faster. The measured spectra are compared with the calculated spectra at the DB's high-speed test section.
