摘要
利用微位移传感器研制了磁致伸缩测量仪,测量了Ni和Dy-Tb-Fe样品的磁致伸缩,实验结果表明该磁致伸缩测量仪器可用于测量棒材磁致伸缩材料.
Magnetostrictive apparatus based on micro-displacement sensor had the characters of vi- sualization, lower power consumption, high accuracy and adjustable magnetic field in two directions. The development, measuring method of magnetostrictive material and structure of magnetostrictive apparatus were introduced in this paper. Using this apparatus, magnetostrictive curves of Ni and Dy- Tb-Fe were measured. The apparatus could be used in virgulate magnetostrictive materials test.
