DESIGN OF FERROMAGNETIC SHAPE MEMORY ALLOY COMPOSITES AND ACTUATORS INCORPORATING SUCH MATERIALS

摘要

The present invention employs an optimized cross-sectional shape for a ferromagnetic shape memory alloy (FSMA) composite that is used in a spring- type actuator, an improved hybrid magnetic trigger for use in FSMA based actuators, an a FSMA composite based spring type actuator, an a FSMA based spring type actuator including a stack of triggering units and FSMA springs, a FSMA composite based torque actuator. The invention also includes a model th at can be employed to evaluate different materials being considered as componen ts a FSMA for a FSMA composite used in either a FSMA based torque actuator or a FSMA spring actuator.
