Abstract
A shock damper is disclosed. The shock damper may have a variable shear control apparatus through which a shear-thickening fluid may flow. In this manner, the shock damper may compress at different rates for different applied impulse forces, in response to the changing viscosity of the shear-thickening fluid.
Claims18
A shock damper comprising:
- a cylinder;
- a piston housed at least partially radially within the cylinder;
- a variable shear control apparatus housed at least partially radially within the cylinder, the variable shear control apparatus comprising:
- a first orifice;
- a second orifice;
- and
- a shear path disposed between the first orifice and the second orifice;
- and
- a shear puck, wherein the shear path is disposed within the shear puck, and
- wherein a shear-thickening fluid travels through the shear path in response to the piston at least one of extending or compressing.

A method of operating a shock damper comprising:
- translating a variable shear control apparatus comprising a first orifice and a shear path in response to a piston at least one of extending or contracting,
- wherein the shear path is disposed within a shock shim stack and comprises a path shape;
- deflecting the shock shim stack in response to the translating;
- changing the path shape in response to the deflecting;
- and
- directing a shear-thickening fluid into the first orifice and through the shear path in response to the translating;
- varying a viscosity of the shear-thickening fluid in response to the directing;
- varying the viscosity of the shear-thickening fluid further in response to the changing the path shape;
- and
- damping the at least one extending and retracting in response to the varying.
