【摘要】：為設(shè)計(jì)圓筒狀超磁致伸縮致動(dòng)器(GMA),采用基于磁路的方法對(duì)圓筒狀超磁致伸縮材料(GMM)內(nèi)的磁場(chǎng)強(qiáng)度進(jìn)行計(jì)算,基于Maxwell軟件建立了圓筒狀GMA的3D模型并對(duì)磁路結(jié)構(gòu)中各部件尺寸及GMA筒內(nèi)構(gòu)件的磁導(dǎo)率對(duì)磁場(chǎng)的影響進(jìn)行了仿真研究。結(jié)果表明:在閉合的磁路結(jié)構(gòu)中,對(duì)于給定的線圈匝數(shù)和激勵(lì)電流,GMM筒中磁場(chǎng)強(qiáng)度大小受GMM筒軸向長(zhǎng)度影響較大且為負(fù)相關(guān)。磁場(chǎng)均勻性方面,影響較大的是穿過圓筒狀GMA構(gòu)件的磁導(dǎo)率和導(dǎo)磁環(huán)軸向長(zhǎng)度,二者均與磁場(chǎng)不均勻度正相關(guān)。
[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.
