Global view on dynamics of impact oscillator
Peterka F.
pages 207 - +7p, full text

Impact oscillator is the simplest mechanical system with one degree of freedom, the periodically excited mass of which can impact on the stop. The aim of this paper is to explain the dynamics of the system, when the stiffness of the stop changes from zero to infinity. It corresponds to the transition from the linear system into strongly nonlinear system with rigid impacts. The Kelvin- VOigt and piecewise linear model of soft impact was chosen for the study. New phenomena in dynamics of motion with soft impacts in comparison with known dynamics of motion with rigid impacts are introduced in this paper.
