Mobility Testing

In mobility testing, accelerance, mobility and compliance functions are calculated. For structures with well-separated modes, estimation of natural frequencies and damping ratios is possible. Often done during troubleshooting using hammer testing.

The Best of Two Worlds

“Besides electrical detection systems, numerous research groups have demonstrated the usefulness of the optical fibre technology to monitor railway infrastructures. With their use, one can determine the structural health of the tracks and its evolution with time, while measuring the traffic. And as such, the maintenance operations can be improved, increasing both the safety level and the availability.”
