IN-PHASE AND ANTI-PHASE SYNCHRONIZATION OF OSCILLATORS WITH HUYGENS ’ COUPLING

In this experimental study, the synchronized mo-tion observed in pairs of nonlinear oscillators coupled through a suspended rigid bar, is analyzed. In parti-cular, the dynamics of two mass-spring-damper osci-llators and the dynamics of two van der Pol oscillators are considered. It is shown that in both cases, the os-cillators may exhibit in-phase and anti-phase synchro-nization. The experiments are executed in an experi-mental setup, consisting of two mass-spring-damper-oscillators coupled through a suspended rigid bar. A relation between the obtained results and Huygens ’ ex-periment of pendulum clocks is emphasized. Key words Synchronization, Huygens ’ coupling, nonlinear osci
