Oscillator with Hertz's model of soft impacts
František Peterka
pages 221 - +3p., full text

Dynamic properties of the mechanical system with one degree of freedom containing soft stop are investigated. Dynamical impact model respects the non-linearity of the restoring contact force between solid bodies as function of deformation according to the Hertz theory. The explanation of the system motion behaviour, when static clearance decreases up to negative values, which express the static prestress, is the main aim of this paper. This process is explained in more detai using phase trajectories, time series and Poincare maps.
