【Abstract】 The work method of one way SMA actuatorwas investigated. Based on the basic law of thermo- dynamics,the transform model of power/energy and thermal/energy was constructed,the effects of char- acteristics of SMA to the outputcharacteristicsof the actuator were analyzed. Finally,a one way SMA ac- tuator design method based on the maximum work/energy transform efficiency was presented,and the quantitative relationship of actuator’s outputproperty,driving component’s property and actuator’s initial state were constructed.更多还原
