Semi-active Damping Device Based on Superelastic Shape Memory Alloys

Technique and some study results of shape memory alloy-based damping device functional parameters

“…Due to their superelastic properties appearing under temperature which is over the austenitic transformation completion temperature the shape memory alloys have been widely used for damping devices in construction to reduce the dynamic loading of building structures elements [8,9], bridges [10,11], under operational loading or earthquakes conditions.…”

Thermomechanically coupled analysis and experimental investigation of morphing structures with shape memory alloy actuators operating under partial transformation with a focus on active load control

“…An attractive field of study for SMA dampers is civil engineering applications. Cladera and coworkers [12] focused on use of iron-based SMAs and provided an overview of their potential, while Lobo et al [13] developed the concept of a semi-active damping device for seismic protection of structures exhibiting non-linear behaviour. Comparison between SMA vibration dampers and conventional devices has been performed by Gur et al [14], according to whom, it was proved that SMAs provide higher control efficiency.…”
