【摘要】:提出了一種基于愛潑斯坦方圈族(包括標準25cm愛潑斯坦方圈、縮比的17.5cm和20cm愛潑斯坦方圈)和二級加權處理方法對愛潑斯坦測試數(shù)據(jù),包括有效磁路長度、比損耗、勵磁功率,進行處理的晶粒取向電工鋼磁性能擴展模擬方法。詳細地考察了勵磁頻率、試樣剪切角度和環(huán)境溫度對愛潑斯坦方圈測量結(jié)果的影響。研究結(jié)果表明,利用本文提出的愛潑斯坦方圈組合以及二級加權處理技術,可以有效地建立取向電工鋼損耗模擬模型,從而更加準確地確定了取向電工鋼的損耗,改善并提高了愛潑斯坦磁性能測試數(shù)據(jù)的應用價值。
[Abstract]:Based on the Epstein square circle family (including standard 25cm Epstein square loop, reduced ratio 17.5cm and 20cm Epstein square loop) and the two-stage weighted processing method, the effective magnetic circuit length, specific loss and excitation power are included. The simulation method of magnetic properties expansion of grain oriented electrical steel is presented. The effects of excitation frequency, sample shear angle and ambient temperature on the measurement results of Epstein circle were investigated in detail. The results show that the loss simulation model of oriented electrical steel can be established effectively by using Epstein square circle combination and two-stage weighted treatment technology, and the loss of oriented electrical steel can be determined more accurately. The application value of Epstein magnetic performance test data is improved and improved.
