摘要
无取向电工钢片旋转磁致伸缩的准确测量对减小电机铁心的振动研究具有重要意义。本文利用二维磁特性装置和玫花型电阻应变计开发了一台用于研究电工钢片旋转磁致伸缩特性的实验测试系统。讨论了应变计在样片尺寸及其粘贴位置的变化对测量结果的影响,分析了一个磁化周期内旋转磁致伸缩的动态特性,仿真计算了一台同步发电机铁心的磁致伸缩变形。研究表明,电工钢片旋转磁致伸缩特性大于交变磁化引起的磁致伸缩,而旋转磁化轨迹决定了旋转磁致伸缩的特性。
The precise measurement about the rotational magnetostriction in the non-oriented electrical steel sheet is significant for the research on reducing the vibration of iron core in the electrical motor. By utilizing a two-dimensional magnetic properties device and a rosette foil resistance strain gauge, this paper develops an experimental tester to investigate the rotational magnetostrictive property of electrical steel sheet. The effects of the paste position and size of the strain gauge on the measurement results are discussed, the dynamic properties of the rotational magnetostrictive strain within one magnetization cycle are analyzed, and the deformation of a synchronous generator core model caused by magnetostriction is simulated. The results show that the rotational magnetostriction is greater than the alternating one and strongly dependent on the shape of magnetization trajectories.
