非晶態(tài)金屬也稱為金屬玻璃或玻璃金屬,是一種固體金屬材料,通常是合金,具有無序的原子尺度結構。大多數(shù)金屬在固態(tài)狀態(tài)下都是結晶的,這意味著它們有高度有序的原子排列。非晶態(tài)合金目前最重要的應用是在工頻和一些高頻變壓器、高效率、低磁化損耗的變壓器中。非晶態(tài)合金材料因其技術應用前景廣闊而受到人們的關注。本文采用二維單片測試儀和數(shù)據(jù)采集裝置,測量了一維交變和二維旋轉磁場中磁通密度B與磁場強度H的關系。提出了一種測量非晶合金材料中磁通量和磁場強度分量的方法。本文在50赫茲頻率的不同外加磁場激勵下,對非晶合金樣品的B和H進行了測量。通過對測量結果的對比分析發(fā)現(xiàn):在低通量密度（0.35 T）下的測量中,Bx-Hx和ByHy磁滯回線的形狀幾乎相同,在增加勵磁電流后,兩個方向的磁滯行為發(fā)生了變化。在測量磁通密度達到0.88 T時,這種現(xiàn)象更加明顯,直到在y方向的磁通密度達到1.85T和X方向1.73 T,材料達到磁飽和值。本文采用Jiles-Atherton磁滯模型模擬了非晶態(tài)合金的磁滯特性。主要工作涉及用交變磁場模擬磁滯特性并與交變磁場測量B-H結果進行對比。仿真結果表明,JilesAtherton模型具...
