Figures

Grahic Jump Location
Typical force versus displacement loading and unloading curves for the ICON and TT Pylon. The ICON was outfitted with an i6 spring and the TT Pylon with a Purple spring.
Grahic Jump Location
Damping force versus frequency for the ICON (n=4, mean ± S.D.) and TT Pylon (n=3, mean ± S.D.). Trend lines, R2 values, and equations represent the result of a least squares linear fit of each data set.
Grahic Jump Location
Damping force versus square root of velocity for ICON (n=4, mean ± S.D.) and TT Pylon (n=3, mean ± S.D.)
