| Abstract: | The actuating characteristics of NiTi SMAs, including the relation between actuating force and temperature, actuating force and power, actuating and the switchover frequency of power, are systematically studied. The dynamic or static strains sensing properties of NiTi wires are tested. The applications of NiTi SMAs in vibration engineering are systematically researched. The results indicate that NiTi SMAs can control the vibration effectively in the very low frequency range(less than 1 Hz). The active vibration control by means of NiTi SMAs with signal processing unit could be achieved. |
