尺寸效应对磁滞回和磁化强度影响的试验研究

Experiment study on the influence of size effect for magnetism hysteresis curve and magnetization intensity

磁滞回环是铁磁材料的重要性能。通过对Q235钢的不同尺寸的模型试件进行磁力耦合试验研究,分别得出不同磁力状态下的磁滞回曲线以及模型尺寸与磁化强度之间的关系曲线。反映了模型构件的尺寸效应对磁滞回性能以及磁化强度的影响规律。

Hysteresis loop of magnetism is the more significant performance for ferromagnetic material.The difference size test specimen was studied on basis of experiment of magnetic coupling.The curve of relationship between model size and magnetization intensity is obtained and hysteretic curve of magnetism is described in the different condition.The result of testing is shown that the influence of law is reflected on basis of between dimensional effect of model test specimen and performance of magnetism hysteretic and magnetization intensity.
