Prediction for buildings and singular cases by hybrid methods (experimental / numerical). Prediction of the effect of corrective solutions, such as blankets under ballast, floating slab track, low rigidity fixings ... Vibration measurements on tracks, tunnels, ground surface and buildings according to ISO 2631, ISO 10815 and ISO 14837. Dynamic characterization of low and high frequency tracks and components (ISO 10846, UNE 13481, UNE 13146, DIN 45673-5). Predictive models for interaction problems between pantograph and catenary. Specialty in rigid catenary. EN 50367 and EN 50318.

• Prediction of noise and vibrations induced by construction activities in nearby buildings. Experimental measures.

• Design of vibration energy reuse systems for remote sensing systems.

• Predictive maintenance procedure based on acoustic emission (very high frequency vibration). The detection of structural faults by acoustic emission has the advantage that it detects changes in the microscopic phase and allows maintenance tasks to be anticipated well in advance. This technique can be applied for the detection of multitude of phenomena, such as leak detection, structural integrity, corrosion detection.
