| Zusammenfassung |
| In the present study the character of slip regimes in laboratory
spring-slider system under weak external periodical forcing has been
investigated. We report the experimental evidence of phase synchronization
(PS) in a slip dynamics, induced by the external periodic electromagnetic
(EM) impact. The quality of synchronization depends on the intensity and
frequency of the applied field; the corresponding Arnold's tongue region is
constructed. Application of special techniques (measuring phase differences,
phase diffusion coefficient, Shannon entropy, Recurrence Quantification
Analysis) allows quantitative assessment of the strength of synchronization
of microslips with EM impact. It is also shown that the character of power
law relationship in acoustic emission amplitude (energy) distribution also
undergoes significant changes at changing excitation intensity. |
