基于简化的取向硅钢片模型,系统地对不同的交流激励下的硅钢叠片内铁损、交链磁通和空气中指定位置的法向漏磁的分布进行了\"单片级\"的测量,并建立了相应的硅钢叠片级问题的三维有限元分析模型,进行了大规模的数值计算分析。模型实验和数值分析的结果表明垂直进入硅钢片的漏磁通和损耗呈现浅透入的特点,在硅钢片内引起的涡流损耗在总铁损中占据了\"举足轻重\"的份额。用电磁场有限元分析软件MagNet瞬态场时步法计算结果与测量结果相吻合,说明本文方法研究复杂的硅钢叠片问题的有效性。 The measurement and 3D finite element analysis of the iron loss,interlinkage flux inside the laminated silicon steel sheets and the magnetic flux densities at the specified positions are carried out based on a verifying silicon steel sheet model.The modeling results show that the leakage flux vertically through the silicon steel sheets has the peculiarity of shin effect,and the eddy current loss caused by the AC leakage flux is a significant component of the total iron loss.The calculated result... 

以质量分数为25%的丙烯酸乳液MC-102、15%Al(H2PO4)3溶液、0.01%H3BO3、0.01%Zn(Ac)2·2H2O和2%二乙二醇丁醚组分,在不同固化工艺下制备涂层。极化曲线和电导率测试发现300℃处理60 s得到的涂层具有良好的耐腐蚀性和绝缘性;水煮实验证明该涂层具有良好的耐水性;断口线扫描发现涂层具有良好的附着性。 A formula comprising MC-102 acrylic emulsion 25%,aluminium dihydrogen phosphate15%,boric acid 0. 01%,zinc acetate dihydrate 0. 01% and diethylene glycol monobutyl ether 2% was used to prepare coatings via different treatment process. The conductivity test and polarization curves revealed that a coating cured at 300 ℃ for 60 s showed good insulative and anticorrosive properties. The water boiling test indicated that the said coating had good water resistance. A cross section of the coating was in...
