Vibration-Based Damage Detection on Railway Wheel Tires

نویسندگان

چکیده

Die Verkehrswende bedingt einen Ausbau des Schienen-Personenverkehrs. Eine in situ Schadenserkennung während Betriebs kann Beitrag zur Kapazitätserhöhung und Sicherheit im Schienenverkehr liefern. Im Vortrag werden Forschungen bezüglich einer schwingungsbasierten, zerstörungsfreien Methode Detektion von Radreifenschäden vorgestellt. Über eine Transferpfadanalyse (TPA) wird auf den Körperschall jedes Rades der Überfahrt rückberechnet. Mit dem synthetisierten mittels akustischen Resonanztests die Schadensidentifikation durchgeführt.

Impacts of Wheel–rail at Railway Turnouts

Investigation of vertical vibrations of a railway turnout is important in designing track components under moving loads of trains. In this paper, the turnout is simulated by a linear finite element model with modal damping. A section of the turnout has a length of 36 sleeper spans surrounding the crossing. Rails and sleepers are modeled with uniform Rayleigh-&#10Timoshenko beam elements. The ra...

Unsupervised Learning Methods for Vibration-based Damage Detection

The basic premise of vibration-based damage detection is that damage will significantly alter the stiffness, mass, or energy dissipation properties of a system, which, in turn, alter the measured dynamic response of the system. Although the basis for vibration-based damage detection appears intuitive, its actual application poses many significant technical challenges. A fundamental challenge is...

Performance of Vibration-Based Damage Detection Methods in Bridges

The important advances achieved in the modal identification, sensors and structural monitoring of bridges have motivated the bridge engineering community to develop damage detection methods based on vibration monitoring. Some of these methods have already been demonstrated under certain conditions in bridges with deliberate damage (Farrar et al., 1998). However, the performance of these methods...
