High codimension bifurcation

Web6 de mar. de 2024 · The organizing center of bifurcation set is the cusp of codimension 3, originating from which there exist a series of bifurcations with lower codimension, such as codimension-1: saddle-node, Hopf, homoclinic bifurcations and bifurcation of a double limit cycle; codimension-2: Bogdanov–Takens bifurcation, degenerate Hopf … Web22 de mar. de 2024 · Abstract. Natural and artificial flapping wing flyers generally do not exhibit chaos or aperiodic dynamic modes, though several experimental and numerical studies with canonical models of flapping foils have reported inevitable chaotic transition at high ranges of dynamic plunge velocity (⁠ κ h ⁠).Here we considered the idealized case of …
