A Forced Damped Oscillation Framework for Undulatory Swimming Provides New Insights into How Propulsion Arises in Active and Passive Swimming
Figure 7
(a) The first few fundamental deformation modes of an undulatory swimmer.
These modes represent the underdamped oscillatory eigenvectors of the system (: first deformation mode;
: second deformation mode;
: third deformation mode). (b) Amplitude or “weights” of various fundamental deformation modes during muscle activated swimming in the linear regime.
