During the construction of Line 5 of the São Paulo Metro, we had the privilege of carrying out an impressive test at LAEDE on a full-size prototype of the permanent track of this line. This slab, 14 meters long and weighing a surprising 40 tons, was built inside our laboratory for a unique experiment.

The video below shows the moment when the prototype passes through the natural frequency and enters resonance when subjected to Vibrodina. It is surprising that a slab with such dimensions and weight can move in such a way.

The objective of the test was to confirm the efficiency of the vibration attenuation system to mitigate the impacts produced by the passage of trains on the magnetic resonance equipment of the Hospital São Paulo, located very close to the track.

This world-first system was conceived and designed by IEME Brazil with devices custom-made by Vibtech.

This is yet another example of IEME and LAEDE’s commitment to technological innovation and engineering excellence. This is how we transform challenges into high-impact solutions for Brazil and the world!
