摘要 磁致伸缩是引起非晶合金电机振动噪声显著增大的主要原因之一。基于压磁方程建立了磁致伸缩引起的非晶合金圆环铁心振动解析模型。解析模型以振动位移为求解变量,采用分离变量法求解振动微分方程。解析模型可用于计算磁致伸缩引起的非晶合金铁心振动位移和振动加速度。通过测试不同加工工艺非晶合金铁心样品的振动,得出叠压和卷绕、浸漆和退火对非晶合金铁心振动的影响规律,确定不同加工工艺非晶合金铁心振动计算修正系数。本文研究工作为非晶合金电机振动噪声的研究奠定了基础。

Abstract:An important source causing vibration and noise of machines with amorphous metal cores (AMCs) is magnetostriction effect of the magnetic material. In order to calculate the vibration due to magnetostriction, an analytical model for AMCs is set up based on piezomagnetic equations. Taking the vibration displacement as variable, the oscillatory differential equations are solved by the variable separation method. This analytical model can be used to predict vibration displacement and vibration acceleration of AMCs. Then the effect of producing processes including stacked and wound, dipped and annealed on vibration in AMCs was examined using measurements of vibration acceleration in AMCs, and related coefficients were also obtained. The outcomes lay a solid foundation for research on vibration and noise of machines with AMCs.
