一个简单的质量-弹簧系统在矩形波的周期性扰动下受到恒定力的作用。在以前的研究中,我们得到了这种扰动的周期-振幅平面的范围,其中轨迹是滑动而没有接触损失的,它被分为两部分,一部分存在无限多个平衡状态而没有周期解,另一部分存在周期解而没有平衡状态。目前的工作重点是在这两个部分之间的过渡。在整个过渡线上,存在一个单一的平衡态。不平衡的初始数据要么导致一个周期轨迹,要么导致一个趋向于平衡的轨迹,要么导致一个周期解,要么在有限时间内,要么在无穷时间内。
A simple mass-spring system is submitted to a constant force in addition to a periodic perturbation of rectangular wave shape. It has been obtained in a previous study that the range of the period-amplitude plane of this perturbation, where the trajectories are sliding with no loss of contact, is divided into two parts, one in which there exist infinitely many equilibrium states and no periodic solutions, and another one where there exist periodic solutions and no equilibrium states. The present work focuses on the transition between these two parts. All along the transition line, there exists a single equilibrium state. Initial data out of equilibrium lead either to a periodic trajectory, or to a trajectory, which tends to the equilibrium or to a periodic solution, either in finite time or at infinity.
