With shape memory function of new smart material, the magnetic control properties of magnetic shape memory alloy could be used to fabricate intelligent actuators for vibration control of reticulated shell structure. The major performance parameters of the microstructure of the materials has been considered in the functional relationship between the magnetic field and strain model of traditional magnetic shape memory alloys(MSMA). But the magnetic field of MSMA do not considered, induced strain and pre-pressure, ambient temperature and other factors, which is a mutual restraint relationship and coupling. Selected Ni53Mn25Ga22, in this paper, as the material for the research on deformation under the action of temperature, magnetic field, pressure coupling effect, and according to the test data designed a MSMA actuator drive.
