摘要
提出了超磁致伸缩材料(Giant Magnetostrictive Material,GMM)执行器的电-磁-机三场耦合分步有限元模型。此模型采用分步方法来建立,首先计算线圈的磁场,然后计算GMM中磁-机耦合场。通过COMSOL Multiphysics 3.4软件中的三个模块来实现所建模型。最后运用此有限元模型对GMM智能构件进行性能分析,得到的仿真结果与实验结果吻合,说明提出的有限元模型有利于GMM应用设计。
A coupled electric-magnet-mechanic finite element model for giant magnetostrictive material actuator is proposed. The finite element model is realized by step. The magnet field is calculated firstly, and then the magnet-mechanic coupled field is cal- culated. The model is calculated by three parts in COMSOL Multiphysics 3.4. The model is used for giant magnetostrictive materi- al component property calculation. The simulation is agreed with experiment. The proposed model could be used for GMM design.
