| Abstract: | A kind of constitutive relationship of shape memory alloy (SMA) is introduced. The principle of SMA damper is discussed, and a kind of SMA damper, for vibration control of frame, is designed and produced. 8 SMA dampers are fixed on a 2 story frame. Vibration experiment data of frame without SMA dampers and with SMA dampers are tested. It is found that vibration energy dissipation ability of SMA damper is notable, and such kind of SMA damper can obviously modify the natural frequencies of frame structure too. |
