Deformation Units

Crash Energy Management inside the coupler
  • Deformation-tube

Deformation elements are an extremely robust and efficient component for energy absorption. Energy is absorbed as a tube expands (or collapses) over a mandrel, creating a highly repeatable structural plastic deformation that, together with friction, determines the deformation force.

The correlation between static and dynamic tests shows that deformation tubes are not velocity dependent.

Available Deformation Units

  • Deformation tubes
  • Deformation tubes behind pivot anchor
  • Cold Drawn Bars
