Abstract
A compression-force spike reduction system for a strut includes a first chamber and a second chamber, an orifice plate disposed within the strut between the first chamber and the second chamber, a hydraulic fluid disposed within the first chamber and the second chamber, and a compressible portion disposed in the second chamber. The orifice plate includes at least one orifice configured for the hydraulic fluid to flow through. During compression or extension of the strut, hydraulic fluid is exchanged between the first chamber and the second chamber. The compressible portion contains a compressible medium configured to buffer spikes in compression force of the strut. A compression-force spike reduction method includes filling the second chamber partially with the incompressible hydraulic fluid, and filling a remaining portion of the second chamber with a compressible medium.
