| Abstract: | In this paper, a new type of shape memory alloy（SMA） damper is proposed based on experimental investigation on NiTi SMA. A theoretical model has been developed from the sectionally linearized superelastic restoring force model of SMA, and a detailed experimental investigation has been carried out to get a full understanding of working performance of the damper. The correctness of the theoretical model is verified by a pseudo-dynamic experiment, and the experimental result shows that the SMA damper has a good energy dissipation ability. |
