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。
Magnetic control shape memory alloy(MSMA)'s magnetomechanical performances were studied with tests to establish a magnetomechanical constitutive model among pre-pressure,magnetic field,and strain.The MSMA actuator operating principle and its construct were systematically analyzed,as well,the corresponding relationships between magnetic field and actuating performance were studied with tests.The constitutive model of a MSMA actuator was obtained.A active control system was integrated and developed.Aiming at a Kewitte type model structure,the control performance test of the active control system was conducted.The results showed that MSMA active control system can effectively control seismic response of a space latticed shell structure.
