Passive Attenuation of Mechanical Vibrations with a Superelastic SMA Bending Springs: An Experimental Investigation
This work presents an experimental study related to the mechanical performance of a special Door Storage design spring fabricated with a superelastic shape memory alloy (SMA-SE).For the experimental testing, the spring was coupled in a rotor machine, aiming to attenuate the mechanical vibration when the system went through a natural frequency witho
