Mechanical snubber

[2] When an impulse event occurs, the snubber becomes activated and acts as a restraint device.

The device becomes rigid, absorbs the dynamic energy, and transfers it to the supporting structure.

When a disturbance occurs that exceeds the acceleration threshold of the snubber, the ball screw and drum produce angular momentum to the inertia mass.

The inertial resistance of the mass engages the resilient capstan to tighten around a hardened mandrel, which is part of the structural tube.

During standard operation, the associated acceleration is far below the threshold limit of the snubber and will not activate the capstan spring.
