Abstract Smart magnetostrictive device based on magnetostrictive effect of giant magnetostrictive materials has a displacement output precision of submicron level to provide a new driving solving scheme for precision and ultra precision machining fields.This precision micro-driving process is realized with the functionality of smart materials.However, in working process of a smart magnetostrictive device, coil’s Joule heat dissipation, materials’ hysteresis and eddy current dissipation may make its temperature rise and may be accompanied by thermal deformation of materials and instability of magnetostrictive coefficient to seriously affect the system’s output performance.Here, temperature variation characteristics of a giant magnetostrictive actuator (GMA) were analyzed deeply.A passive compensation mechanism for thermal deformation was proposed to design a GMA with thermal deformation self-compensation function.Test results showed that GMA’s heating forms and heat sources depend on excitation current forms and working frequency; the designed GMA can automatically compensate its thermal deformation in its working process; the study results can provide a way to improve working accuracy of magnetostrictive devices applied in precision and ultra precision machining fields.
