Abstract
A shock absorber includes a first end configured to be mechanically fastened to a first component, a second end configured to be mechanically fastened to a second component, a main body, a main shaft, and a primary piston. The primary piston configured to move within the main body and further configured to provide a first damping force by movement of a fluid through the primary piston while the main shaft moves a first distance. The shock absorber also includes a deformable solid material arranged in the main body. The primary piston configured to further move within the main body and further configured to provide a second damping force by deforming the deformable solid material after the main shaft moves the first distance.

A shock absorber configured to reduce rotational velocity, comprising:
- a first end configured to be mechanically fastened to a first component;
- a second end configured to be mechanically fastened to a second component;
- a main body that is attached to the first end;
- a main shaft that is attached to the second end;
- a primary piston configured to be received in the main body;
- the primary piston being attached to the main shaft and the primary piston being further configured to be movable with the main shaft;
- the primary piston configured to move within the main body and further configured to provide a first damping force to reduce rotational velocity by movement of a fluid through the primary piston while the main shaft moves a first distance during rotational movement at a first rate of speed of one of the first component and the second component;
- a deformable solid material arranged in the main body;
- and
- the primary piston configured to further move within the main body and further configured to provide a second damping force to reduce rotational velocity by deforming the deformable solid material after the main shaft moves the first distance during rotational movement at a second rate of speed of one of the first component and the second component, the second rate of speed of one of the first component and the second component being greater than the first rate of speed of one of the first component and the second component,
- wherein one of the first component and the second component comprises a fixed structure;
- and
- wherein another one of the first component and the second component comprises a movable structure.
A process of implementing a shock absorber configured to reduce rotational velocity, comprising:
