Introduction,tions due to the combined effects of friction, impact and weight. The motion of this toy is greatly influenced by simultaneous impacts, which cause discontinuous bifurcations ([836], [364], [837], [838], [579], [581], [365], [578]). The dynamics of the woodpecker toy can be analyzed with a one-dimensional Poincaré map.作者: Atheroma 時(shí)間: 2025-3-26 05:37
