Накратко на български

Железническите мостове се анализират чрез вибрациите на преминаващите по тях влакове, вместо чрез сензори по самата конструкция. Това помага за по-евтино и мащабно следене на състоянието на остарелите съоръжения, за да се гарантира безопасността на транспорта.

On-Board Monitoring of In-Service Trains for the Structural Health Monitoring of Railway Bridges

Railway bridges represent critical components of the European transport network, enabling safe and efficient mobility of passengers and goods across the continent. Many bridge assets currently in service are ageing and require continuous monitoring in order to ensure safety, optimise maintenance costs, and support the transition towards more sustainable and resilient infrastructure systems. Conventional structural health monitoring systems are often expensive to install and maintain, which limits their large-scale deployment across extensive railway networks. Recent research has demonstrated the potential of so-called mobile monitoring approaches, where vibration measurements recorded on trains crossing a bridge are used to estimate the structural properties of the bridge without installing sensors directly on the structure. Such approaches could enable cost-efficient monitoring of a large number of bridges using existing railway vehicles, but several scientific and technical challenges still prevent their reliable use in practice. These include the influence of operational variability, environmental conditions, modelling uncertainties, and the difficulty of extracting structural information from indirect measurements. The objective of this project is to develop advanced methodologies for the identification and monitoring of railway bridge dynamics using both direct measurements on the structure and indirect measurements obtained from passing trains. The project aims to establish robust data-driven and physics-based approaches to reliably estimate bridge modal properties, integrate monitoring data with numerical models, and quantify uncertainty in the identified parameters. The project pathway to impact focuses on enabling scalable and cost-efficient monitoring strategies for railway infrastructure. The expected results support infrastructure managers, engineering companies, and public authorities in improving maintenance planning, reducing life cycle costs, and increasing the safety and reliability of the European railway network. The project contributes to European priorities related to sustainable mobility, digitalisation of infrastructure, and resilience of transport systems.

Цел на проекта

Railway systems are expanding rapidly worldwide as a 'green' means of transportation. Such rapid expansion poses a challenge toguaranteeing safety and ensuring the quality of railway systems. Continuous monitoring of tracks and rail bridges can help diagnoseand prognose damage timely, increasing railway transportation reliability. In this project, we focus on rail bridges, whose conditionassessment traditionally relies on a static network of sensors. Although well-established, this technique lacks portability, entailsconsiderable cost and effort, and, crucially, inhibits continuous monitoring, as the lifespan of sensors is generally smaller than that ofthe bridge. To tackle these limitations, indirect monitoring practices have recently gained attraction. Such methods extract thedynamic properties of bridges via measurements from traversing vehicles by exploiting the Vehicle-Bridge Interaction (VBI) principle.This way they offer mobility and lower installation and maintenance costs. However, the majority of studies on indirect monitoring ofbridges focus on highways. Despite the similarities of VBI modelling between highways and railways, distinct differences (e.g., vehicleand contact models, moving speed, loading patterns) do not allow the direct application of current indirect monitoring methods torailway bridges. Another challenge is the blurring effect of surface roughness, which, simplistically, is typically considered as known oris eliminated. To this end, this project proposes a consistent methodology to continuously monitor railway bridges via On-BoardMonitoring of in-service trains, with a simultaneous characterization of the involved roughness profiles. Accordingly, it proposes ahybrid modelling procedure that considers a VBI model (which represents actual train-bridge systems and considers the roughness ofthe involved track system) fused with vibration measurements collected from traversing trains.
