Double-beam systems consist of two parallel beams coupled through elastic or viscoelastic interfaces, springs or dampers. They serve as fundamental models for a wide range of engineering structures, ...

(Phys.org)—In an attempt to harvest the kinetic energy of airflow, researchers have demonstrated the ability to harvest energy directly from the vibrations of a flexible, piezoelectric beam placed in ...

Shown below is an animation of the response of the pair of beams coupled together with a soft spring. A discussion of the problem and its solution is provided in this video clip. A simulation of the ...
