Fig. 6. Contour plots of the magnitude of the center of mass vertical displacement
relative to the pendulum vertical displacement
(
zcom; A) and the phase relationship between the
center of mass and the hind pendulum vertical displacement (
; B) for the
two-pendulum model of walking. These data are plotted as a function of the
relative mass of the fore pendulum, Mf, and the phase
difference between the fore and hind pendulums,
. Both pendulums have
the same amplitude in all cases. The circled letters correspond to the
combinations of phase and mass distribution in
Fig. 5AD.
