摘要：
Giant magnetostrictive actuator is ideal for fast precision Alignment, but the nonlinear strain caused by temperature rise has serious impact on the control precision. This paper verifies the impact of strain caused by temperature rising on the experimental method, based on analyzing the principle of the giant magnetostrictive actuator. The copper consumption in giant magnetostrictive actuator coil, the iron consumption in the magnetostrictive rod and the corresponding method of inhibiting temperature rise were analyzed by theoretical analysis and finite element simulation.
