摘要:
In one embodiment, a flexural wave absorption system includes a base member connected to a beam that may be subject to flexural waves, an arm member, connected to the base, disposed substantially in parallel alignment with the beam, a mass member connected to a distal end of the arm member, a piezoelectric patch, connected to the arm member, that generates electricity in response to a flexural wave propagating through the beam, and a shunting circuit, connected to the piezoelectric patch, that dissipates electricity generated by the piezoelectric patch to absorb the flexural wave.
