The Parameters Selection of SMA Optically Activated and Its Application
摘要
Shape Memory Alloy (SMA) optically activated is the key lechnology of optical SMA activator,According to the shape memory mechanism of SMA ,researches are done on the activating response time and light wavelength of activating source elc of SMA optically activated to approach the parameters welection of optical activation ,SMA has the optimum efficiecy in the rage of 13 seconds to 27 seconds when SMA is illuminated continusly by wavelength of 675 nm;The power of light wave has a low effect on SMA ;the longer the activating wavelenth ,the quicker the response time of SMA activated ,If the proper activating time and activating wavelength,are adopted,and the structure deformation of composite material of SMA imbedded may be actiely controlled,and ideal effect will be gotten ,The resarch provides an evdence for the design of optical SMA activator and is of great significnce to its application ,Theresarch on smart structure has a wide application prospect.
