摘要 对磁控形状记忆合金材料进行了磁力学性能试验研究,建立了预加压力-磁场-应变等磁力学本构模型;系统地分析了磁控形状记忆合金作动器的工作原理和构造方法,并进行了相应的磁场-作动性能试验研究,得出了磁控形状记忆合金作动器的静/动力本构模型,集成和开发了主动控制系统,并对一凯威特型模型结构进行了相应的控制性能试验。结果表明,研发的磁控形状记忆合金主动控制系统可有效控制网壳结构的地震响应。 Magnetomechanical performance were studied in the Magnetic Control Shape Memory Alloys (MSMA) by experiments to establish magnetomechanical constitutive models about add pressure, magnetic field, and strain. The MSMA actuator operating principles and its construct are systematically analyzed and the corresponding relationships between magnetic field and actuator performance are tested as well, as a consequence, the static/dynamic constitutive model of MSMA actuator could be concluded and the active control system is integrated and developed, on the basis of the Kewitte type model structure, the control performance test experiment of the active control system is conducted as well. The results shows that the MSMA active control system can effectively control the seismic response of space latticed shell structure.
