基于改进多尺度动态J-A模型的无取向硅钢磁致伸缩特性模拟
Simulation of Magnetostrictive Properties of Non-oriented Silicon Steel Based on Improved Multiscale Dynamic J-A Model
摘要
Abstract
To simulate the magnetostrictive hysteresis characteristics of non-oriented(NO)silicon steel in a wide range of magnetic densities under stress,this paper proposes an improved multiscale dynamic magnetostrictive model.Firstly,a simplified multiscale model considering the volume fraction of magnetic domains is proposed to simplify the model and shorten the computation based on the Boltzmann function and the single crystal structure of six magnetic domains;Secondly,the stress-dependent expression of the anhysteretic magnetization obtained from the simplified multiscale model is brought into the inverse J-A model.The correction factors v and γk are introduced to achieve an accurate simulation of hysteresis loops at different magnetic densities.Then,the eddy current field,excess loss field,and irreversible magnetization component are introduced to construct the improved multiscale dynamic magnetostrictive model.Finally,comparing the simulation with experimental results,it is found that the model accurately simulates the dynamic magnetostrictive characteristics under the stresses from 0～2.4 MPa,and it has high simulation accuracy for both the λ-H curve and the λ-B curve.关键词
