Spatio-temporal dynamics of coupled magneto-elastic system

摘要

In this paper the spatio-temporal vibration in a coupled magneto-elastic beam system is discussed experimentally and numerically. The periodical forcing at the end of the beam system induces the several types of vibrations to the magneto-elastic beam through the coupling beams. It is caused by the nonlinearity which depends on the potential well of each magneto-elastic beam and the wave propagation passing through the coupling beams. The temporal vibration of the magneto-elastic beam is explained with relations to the spatial state transition based on the experimental results.
