AN EXPERIMENTAL SPATIOTEMPORAL STATE TRANSITION OF COUPLED MAGNETOELASTIC SYSTEM

In this paper the vibration and the traveling wave in a coupled magnet o-elastic beam system are discussed experimentally, Tile vibration exc ited by the periodical forcing at the beam system propagates to anothe r as a wave through the coupling elastic beams. Each magneto-elastic b eam shows the variety of vibrations caused by the nonlinearity of the potential well and the wave propagation with time delay. The temporal vibration of the magneto-elastic beam is explained with relations to t he spatial stale transition based on the experimental results. (C) 199 7 American Institute of Physics.
