摘要: 将磁致伸缩式惯性冲击电机的动力学模型与基于Jiles-Atherton模型的磁致伸缩材料非线性本构模型相结合,建立磁致伸缩惯性冲击电机的步长及速度预测模型。利用MATLAB / Simulink软件搭建仿真系统,通过仿真可得到惯性冲击电机的位移及速度。搭建实验系统对模型进行验证。仿真与实验结果表明,在驱动电流0.4~4A、驱动频率10~80 Hz的工作区间内,模型预测值与电机实际输出之间的误差不超过15%,能够对磁致伸缩惯性冲击电机的运动性能进行准确预测。

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.

Key words: impact drive mechanism, magnetostrictive materials, non-linear model, dynamic model
