MONITORING VIBRATIONS ALONG BRIDGES IN RAIL TRANSPORT THROUGH THE TRAINSOFT SYSTEM

Enis Berisha

Abstract

Rail transport along specially important objects such as bridges and tunnels is of particular importance. In addition to their importance it also represents a very high-risk hazard, on the grounds that it contains a very weighted load and peoples within this transportation. Bridges and flyovers are critical in many regions, being used over several decades. It is critical to have a system to monitor the health of these bridges and report when and where maintenance operations are needed. Advancements in sensor technology have brought the automated real-time bridge health monitoring system[1]. Monitoring of these processes is very important, Based on that this is part where unfortunately we have almost the highest number of accidents and this makes us really approach such a problem. We have created a device by which we measure the level of vibrations during the train's overtaking on the bridge, through this transition it will record and graphically present which we can then take and analyze. All this data during each move will be recorded on an SD card that is integrated into the device and which we can take at any time depending on our need. If the level of vibration is higher than the normal level then the device will signal the danger of exceeding the vibration level still we have transportation. After we have design this device just for research purposes we are in process to put in some places to test the operation and monitoring through it. Railway and highway bridges are an important part of the transport infrastructure. They represent a major investment for society and an important part of that investment goes to inspection and maintenance. Bridges often constitute bottlenecks in the transport system with few practical alternative routes. As such, closing them for repair, inspection or replacement entails large costs for the users. Furthermore, safety levels in bridges are expected to be higher than in other parts of the transport system. This comes naturally due to the fact that failure of a bridge could have severe consequences in material damage and human lives. Introducing onitoring techniques in its different forms (damage detection, traffic monitoring, reliability assessment, etc.) can save costs by improving the understanding of the structure, thus reducing the need of overly safe assumptions and by granting the possibility to get early warnings of problems that develop[1].
