研究了由非光滑映射描述的动力系统。这是在研究某些物理系统,特别是碰撞振荡器时自然产生的。我们确定了一种新的形式的分叉放牧分叉,并显示(通过例子),这导致复杂的动力学,包括混乱的行为穿插与周期性行为的添加窗口。然后,我们构建了一个规范形式的放牧分歧和分类的动态可以观察到的。文章最后提出了一些有待解决的问题。
We study some dynamical systems described by non-smooth maps. which arise naturally in studies of certain physical systems-especially impact oscillators. We identify a new form of bifurcation-the grazing bifurcation and show (by example) that this leads to complex dynamics, including chaotic behaviour interspersed with period adding windows of periodic behaviour. We then construct a normal form for the grazing bifurcation and classify the dynamics which can be observed. The article concludes with some open problems.
