【摘要】：Jiles-Atherton(J-A)模型在磁化建模領(lǐng)域應(yīng)用廣泛,但不同文獻(xiàn)給出的J-A模型并不一致,致使采用不同表達(dá)式建立的塑性變形磁化模型存在多種版本,其正確性難以甄別.通過(guò)對(duì)無(wú)磁滯磁化方程、能量守恒方程和等效磁場(chǎng)強(qiáng)度方程的梳理與比較,發(fā)現(xiàn)原有模型中存在將磁化強(qiáng)度和無(wú)磁滯磁化強(qiáng)度混用、將不可逆磁化能量等效于全部的磁化能量、等效磁場(chǎng)強(qiáng)度中應(yīng)力磁化項(xiàng)界定不清等問題.在此基礎(chǔ)上,對(duì)上述方程進(jìn)行了修正,推導(dǎo)了基于J-A模型的塑性變形磁化修正模型.將修正模型計(jì)算結(jié)果與原模型計(jì)算結(jié)果、相關(guān)文獻(xiàn)中的試驗(yàn)結(jié)果進(jìn)行對(duì)比,結(jié)果表明:與原有計(jì)算模型相比,修正模型計(jì)算結(jié)果的飽和磁化強(qiáng)度和剩余磁化強(qiáng)度隨塑性變形增加而減小,矯頑力隨塑性變形增大而增大,達(dá)到飽和磁化強(qiáng)度時(shí)的外磁場(chǎng)強(qiáng)度隨塑性變形增大而增大的趨勢(shì)有所減弱,更符合試驗(yàn)結(jié)果,可更準(zhǔn)確地反映塑性變形對(duì)材料磁化的影響.
[Abstract]:Jiles-Atherton (Ja A) model is widely used in the field of magnetization modeling, but the JA model given in different literatures is not consistent, so there are many versions of plastic deformation magnetization model based on different expressions, and its correctness is difficult to be distinguished. By combing and comparing the non-hysteresis magnetization equation, the energy conservation equation and the equivalent magnetic field intensity equation, it is found that there is a mixture of magnetization intensity and non-hysteresis magnetization intensity in the original model, and the irreversible magnetization energy is equivalent to all magnetization energy. The definition of stress magnetization term in equivalent magnetic field is not clear and so on. On this basis, the above-mentioned equations are modified, and the modified plastic deformation magnetization model based on Ja-A model is derived. The calculation results of the modified model are compared with those of the original model and the experimental results in the relevant literature. The results show that: compared with the original calculation model, the experimental results are compared with those of the original model. The saturation magnetization and residual magnetization of the modified model decrease with the increase of plastic deformation, while the coercive force increases with the increase of plastic deformation. When the saturation magnetization is reached, the external magnetic field intensity increases with the increase of plastic deformation, which is more consistent with the experimental results and can more accurately reflect the effect of plastic deformation on the magnetization of materials.
