In this article, on the basis of the shape memory alloy wire wrap wire, by adjusting the controls the current to alloy wire warming deformation, thereby changing the rigidity of the system becomes active control of variable structure, its damping effect better.

In this article foundation, gathers the gold thread for the shape memory to entangle the heating wire, causes through the regulating control electric current to gather the gold thread elevation of temperature to distort, thus the change system rigidity, namely becomes changes the structure initiativ

In this article on the basis of shape memory alloy wire wrapped wire, heating the alloy wire by adjusting the control current deformation, thus changing the stiffness of the system, becomes a variable structure active control vibration better.
