摘要: 激励线圈作为电磁转换构件，主要为GMA提供驱动磁场，调节输入电流大小并控制其输出位移。因此，优化设计激励线圈结构参数、材料选取是提高电磁转换效率和充分发挥GMM特性的关键因素。通过分析GMA的工作原理，将GMM棒中轴线上的磁场强度均匀性作为评价标准和主要设计原则；分析其磁导率选取合适的激励线圈材料并对磁场强度、热损失等重要影响因素进行综合考虑，对激励线圈参数进行优化设计；使用Ansoft Maxwell仿真分析激励线圈的磁路。结果表明磁场分布更均匀，使均匀度提高到98.65%。

Abstract: Exciting coil is the electromagnetic conversion component, which mainly provides the driving magnetic field for Giant Magnetostrictive Actuator (GMA) and controls its output displacement, and can adjust inputting different current. Therefore, optimizing design the structural parameters and selecting appropriate material of the exciting coil is the key factor to improve the electromagnetic conversion efficiency and give full play to the characteristics of Giant Magnetostrictive Materials (GMM) materials. In this study, the uniformity of magnetic field intensity on the center axis of GMM rod is regarded as the evaluation standard and main design principle by analyzing the working principle of GMA. Exciting coil material is selected through analyzing of its magnetic permeability and the design parameters of exciting coil is optimized by analyzing important factors such as magnetic field intensity and heat loss. Finally, the magnetic circuit of excitation coil is analyzed by using Ansoft Maxwell finite element method. The simulation result shows that the distribution of magnetic field is more uniform and its uniformity is improved to be 98.65%. -
