The limit blocks 3051 can ensure that the shape memory alloy rod 305 is always not separated from the piston plate 304 and the end plate 3013 during the tension and compression process.

[0096] The limiting block 3051 is a nut. Both ends of the shape memory alloy rod 305 are provided with threads. The limiting block 3051 is screwed into both ends of the shape memory alloy rod 305 .

[0099] The vibration reduction component of this embodiment is mainly used for vibration reduction of wind power generation equipment sets, and can also be used in vibration reduction systems of equipment such as construction engineering, vehicle engineering, shipbuilding and mechanical engineering.

[0100] When in use, the upper connecting plate 1 and the lower connecting plate 2 of the vibration-damping component described in this embodiment are connected to the equipment. When the equipment shakes, the closing mechanism 4 consumes energy in all directions through internal hinges. When the damper 3 is displaced, the middle sliding plate 302 drives the piston plate 304 to slide back and forth in the outer sleeve 301. Due to inertia, the middle sliding plate 302 and the friction plate 303 rub back and forth to consume energy.

[0101] It is worth noting that the vibration-damping component disclosed in this embodiment is based on a bionic honeycomb-like structure design, and this special structure not only has good load-bearing capacity, but can also achieve favorable nonlinear effects without setting a limit device, so as to better work together with the damper to provide the wind turbine with a larger variable stiffness and a multi-dimensional multiple energy-absorbing vibration reduction mechanism within the limited installation space of the wind turbine cabin.
