Rail Tension
RAIL TENSION
Due to temperature changes, stresses are generated in continuously welded track; their sum exerts a significant influence on track operation safety. The exact knowledge and control of these stresses are therefore indispensable for a safe operational procedure. With our measuring devices, we are able to measure and document these.
Measurement of stresses and Stress-Free Temperature using TRACKSAFE RELEASE
The measuring device TRACKSAFE RELEASE enables measuring mechanical stress state of the track and thus the Stress-Free Temperature. This is carried out non-destructively without any obstruction and can be integrated into the operational procedure of the network operator. Additional track possessions are not required. The TRACKSAFE RELEASE device is used for the:
- Preventive determination of actual Stress-Free Temperature/stress condition
- Control of cw-track production (e.g. final welds, re-establishment of required stress conditions)
- Complete railway inspection.
The service comprises the complete measuring performance, evaluation, and report creation.
Measurement of stresses and Stress-Free Temperature using a strain gauge (s. g.) technique:
The mechanical stress state can be determined using strain gauges alterations. This is possible on railway rails, their components, or other construction parts. Both long- and short-time measurements are possible here.
This method is used, amongst else, during the control of the cw-track production (Stress-Free Temperature) and the subsequent long-time stress monitoring. Presently, projects of national and municipal railway companies are metrologically supported.
Residual stress measurements
Various measuring tasks for the determination of residual stresses, particularly in rails, are taken, using magnetic testing facilities as well as the strain gauge hole-drilling method.
