以高分子材料梁为基体，在梁的两侧面嵌入Ｍ相状态的ＮｉＴｉ合金丝作为驱动组元，一侧面嵌入母相状态的ＮｉＴｉ合金丝作为振动感知组元；建立起振动主动控制系统，实现了系统振动主动控制的计算机仿真．试验结果表明：ＮｉＴｉ形状记忆合金可灵敏地感知系统振动，在低频（小于１Ｈｚ）范围内，可有效抑制振动；试验结果验证了计算机仿真结果的正确性．提出通过增加组内ＮｉＴｉ丝的可控数量，可有效地提高ＮｉＴｉ合金控振频率的上限．探讨了ＮｉＴｉ形状记忆合金应用于结构振动主动控制中所存在的问题． Taking the polymer material beam as the base, the NiTi alloy wire in the M phase is embedded on both sides of the beam as a driving component, and the NiTi alloy wire embedded in the mother phase on one side is used as a vibration sensing component; an active vibration control system is established to realize Computer Simulation of Active Control of System Vibration. The experimental results show that the NiTi shape memory alloy can sense the system vibration sensitively and can effectively suppress the vibration in the low frequency range (less than 1Hz). The experimental results verify the correctness of the computer simulation results. It is proposed that by increasing the controllable amount of NiTi wire in the group, the upper limit of the controlled vibration frequency of the NiTi alloy can be effectively improved. The problems existing in the active vibration control of NiTi shape memory alloy were discussed.
