• Giant magnetostrictive material actuator
• Finite element simulation
• Magnetic flux density

Based on the working characteristics of giant magnetostrictive materials, this paper presents a new kind of giant magnetostrictive actuator; the distribution of magnetic field density of the giant magnetostrictive actuator is simulated by finite element simulation software (ANSYS). By changing the excitation current, the relationship between the internal magnetic field strength of giant magnetostrictive actuator and the excitation current is obtained; the research results show, with the current increasing gradually, the magnetic flux density in the giant magnetostrictive materials also increases, and then, the magnetic flux density will trend to be saturated. In addition, the effect of the additional magnetic field on magnetic flux density of giant magnetostrictive materials is also validated.
