Heat, so as to realize vibration control.The advantage of eddy current damper is：Do not contacted directly between magnet and conductor, nothing is rubbed
Wipe damping and abrasion；Do not influenceed by environment such as temperature；In the absence of situations such as oil leaks, easy to maintain and good endurance.
Semi- active control is a kind of emerging structural vibration control form.Semi- active control passes through attached in seismic isolation device
Add control system, improved the control effect of seismic isolation device, both can guarantee that safety of the building structure under geological process, have again
The advantages of external world in need provides little energy, and stability is high.
