Theoretical Hill-Type Muscle and Stability: Numerical Model and Application

Figure 3

(a) Ten and plots for quick-release contraction experiments using 19 different external forces were recorded. Based on those and plots the force-velocity curve (crosses) was calculated. In direct comparison with the biological experiments (rat gastrocnemius muscle [20]) and the predictions from theory, the artificial muscle data shows a good match for both, with . A hyperbola fit of the artificial muscle data results in [13, 15]. (b) The strength of the presented approach is shown by a comparison of curves calculated for different biological muscle parameters. The respective - curve can be plotted by just taking and values from experiments and calculating the parameters and . The latter two parameters are necessary to build a technical muscle of that respective type.
