We have managed to dampen the wave in less than 8 seconds, a record, and for a year the improvements have been 100%. The weight of the Inoviria CaDOD-100 is less than 5 Kg and is compensated by the presetting of the fall in the center of the opening that can be regulated thanks to the Innoviria CaDOD-100.
The following figure shows the comparison in the response for a catenary span of 9 meters subjected to a manual excitation that introduces an initial energy representative of the one that would incorporate the step of a pantograph to the span analyzed. The difference in response is observed for the same vain, incorporating or not the Innoviria CaDOD-100. The oscillation for the catenary with the Innoviria CaDOD-100 (lower graph) stops before 8 seconds, while for the same catenary without the device (upper graph), the oscillation is maintained for more than 1 minute.
