Abstract: A model of magnetostrictive impact drive mechanism (IDM) was built to predict the step size and velocity, in which the dynamical model and the second order non-linear model of magnetostrictive material based on Jiles-Atherton model were considered. The simulation model was developed by utilizing MATLAB /Simulink software, and the data of IDM's displacement and velocity was obtained based on the model. The experimental system was built to testify the given model. The results illustrate that the error between experiment and simulation results are less than 15% within the range of driving current 0.2~0.4A and working frequency 10~100Hz. The proposed model can be used to predict the motion performance of magnetostrictive impact drive mechanism.
