Abstract: A
hysteric model is represented to describe the dependence of
restoring force on deformation of pseudoelastic SMA. The dynamic
response of the system is investigated by means of mathematical
models. The result shows that this kind of vibration absorbing
system can suppress vibration with large amplitude effectively.
Furthermore, the vibration absorbing system can work in optimum
state by adjusting temperature and using piezoelectric sensors
and actuators.
