考虑磁致伸缩效应时电机定子硅钢片的振动研究
|
Abstract:
为了研究交变磁场下电机定子硅钢片磁致伸缩效应的变化规律，本文首先建立了无取向硅钢片磁–机械耦合数值模型，研究了不同叠压片数无取向硅钢片在交变磁场中表面应力的变化情况，并根据仿真模型搭建了实验平台进行实验。将硅钢片水平放置在线圈一侧，并由绝缘材料固定位置，然后分别对水平放置和倾斜45？放置的无取向硅钢片进行了应变采集和振动测量实验，结果都发现在同一交变磁场下，随着无取向硅钢片叠压片数的增加，无取向硅钢片表面的应变和振动情况逐渐减小，这与仿真结果相符。此结论对电机减振降噪有一定的指导意义。
In order to study the variation law of magnetostrictive effect of motor stator silicon steel sheet under alternating magnetic field, the magnetic mechanical coupling numerical model of non oriented silicon steel sheet is established in this paper, and the change of surface stress of non oriented silicon steel sheet with different number of laminated sheets in alternating magnetic field is studied, and the experimental platform is built based on the simulation model. The non- oriented silicon steel sheet was placed horizontally on one side of the coil and fixed by insulating material. Then the strain collection and vibration measurement experiments were carried out on the non oriented silicon steel sheet placed horizontally and inclined 45？ respectively. The results show that, under the same alternating magnetic field, the strain and vibration on the surface of the non oriented silicon steel sheet gradually decrease with the increase of the number of laminated sheets The true result is consistent. This conclusion has a certain guiding significance for motor vibration and noise reduction.
