Modeling and Experiment of Terfenol-d Driven Composite Cantilever Beam

Vibration model of Terfenol-D composite cantilever beam is established by combining the transverse beam vibration theory with mechanics of composite materials. The structural natural frequency is simulated by COMSOL Multiphysics, simulation results show that First-mode frequency is 54.30 Hz. The prototype experimental is done with the same parameters, First-mode frequency of the composite cantilever beam is 49.70 Hz. The simulation and experimental results show that quality of Terfenol-D patch have little influence on natural frequencies.
