New phenomena of the dynamics of oscillators with impacts, when the stiffness of the stop changes from zero to infinity, are described. Dynamics of one example of the system with soft impacts, as the model of the piercing machine, is explained in more detail by bifurcation diagrams, time series, pha

✦ Synopsis
The excited, one degree of freedom mechanical system with soft impacts, characterised by triangle hysteresis loop, is investigated using numerical simulation. Small viscous damping is assumed. Phenomena of subharmonic motions are explained by regions of their existence and stability in the plane of dimensionless excitation frequency and static clearances. Bifurcation diagrams are evaluated during quasistationary changes of frequency by constant clearance.

Results of a numerical investigation are presented of the behaviour of a mathematical model which approximates the response of a thin metal strip, or beam, held vertically and clamped at its base, which is driven to impact against a motion limiting constraint.

Systems constituted by moving components that make intermittent contacts with each other can be modelled by a system of ordinary differential equations containing piecewise linear terms. We consider a soft impact bilinear oscillator for which we obtain bifurcation diagrams, Lyapunov coefficients, re
