摘要 提出一种依赖矢量磁特性的电工钢片应力测量方法,采用电动推杆实现同时在轧制与垂直于轧制方向对电工钢片施加拉(压)力。优化设计励磁磁轭的尺寸并合理布局以保证测量区域磁场分布的均匀性,提高测量精度。将B探针与双复合H线圈统一装配到电木框架内构成矢量B-H传感器,达到同时测量电工钢片磁通密度B和磁场强度H信号的目的。根据坡印亭定理计算不同磁化条件下电工钢片比总损耗。基于上述方法分别测量了无取向电工钢样品不同磁化角度、轴比以及磁通密度下的矢量磁特性,测量过程中将预拉(压)力矢量的方向设置为与磁化角度一致。根据测量结果总结归纳出电工钢片矢量磁特性的应力依赖演化规律。

Abstract:A novel stress dependent vector magnetic properties measurement method of electrical steel sheet is proposed. The tension or compressive stress is applied by Linear Actuator along rolling and transverse direction. The uniformity of magnetic flux density is guaranteed by optimizing the dimension of magnetic yoke and its arrangement so that the measurement accuracy can be improved. In order to measure the vector magnetic flux density and magnetic field intensity, B probe and double compound H-coil are introduced and assembled inside a frame of bakelite. According to pointing’s theorem, the total specific iron loss of electrical steel sheet under different magnetization conditions can be calculated. Based on the proposed method, the vector magnetic properties of different magnetization angles, axial ratio and magnetic flux density level of the specified non-oriented electrical steel are measured respectively by applying tension or compressive stress along magnetization direction. According to the measurement results, the evolution rule of stress dependent vector magnetic properties of electrical steel sheet is summarized.
