【摘要】：为设计圆筒状超磁致伸缩致动器(GMA),采用基于磁路的方法对圆筒状超磁致伸缩材料(GMM)内的磁场强度进行计算,基于Maxwell软件建立了圆筒状GMA的3D模型并对磁路结构中各部件尺寸及GMA筒内构件的磁导率对磁场的影响进行了仿真研究。结果表明:在闭合的磁路结构中,对于给定的线圈匝数和激励电流,GMM筒中磁场强度大小受GMM筒轴向长度影响较大且为负相关。磁场均匀性方面,影响较大的是穿过圆筒状GMA构件的磁导率和导磁环轴向长度,二者均与磁场不均匀度正相关。
[Abstract]:In order to design the cylindrical giant magnetostrictive actuator (GMAA), the magnetic field intensity in the cylindrical giant magnetostrictive material (GMMM) was calculated by magnetic circuit based method. Based on the Maxwell software, the 3D model of cylindrical GMA is established, and the effects of the size of each component in the magnetic circuit and the permeability of the inner component of the GMA cylinder on the magnetic field are simulated. The results show that: in the closed magnetic circuit structure, For the given coil turns and the magnetic field intensity in the GMM cylinder, the axial length of the GMM cylinder has a significant negative correlation with the number of coil turns. In terms of magnetic field uniformity, the permeability through the cylindrical GMA component and the axial length of the conducting magnetic ring are greatly affected. Both of them are positively correlated with the magnetic field inhomogeneity.
