摘要: 考虑了不同磁介质磁化性能的非线性,并采用介质边界上磁场传播关系对介质边界漏磁的精确描述,利用不等间距网格有限差分数值方法,对矢量磁位描述的轴对称场偏微分方程进行求解,计算出磁流体密封装置中具有非线性、稳态特征的强磁场分布,得出了不同齿数密封装置的磁场分布,克服了磁路法计算中对磁介质磁化性能和漏磁理想化估计带来的误差,计算结果准确、合理、可靠,为密封装置的结构设计提供了设计依据.

Abstract: Magnetic leakage is described accurately by magnetic propagation equation on the boundary of magnetic dielectric and non-linear magnetization characteristic of different magnetic dielectric is considered, the distribution of steady, non-linear and forced axial symmetry magnetic field in magnetic fluid sealing device with different number of the poles is calculated by solving the partial difference equation described by magnetic vector potential, and unequally spaced net finite difference is adopted in the numerical calculation. This method overcomes the error caused by ideal estimation on magnetic leakage and work point of different place in magnetic dielectric in magnetic circuit method, the results are accurate, reasonable, reliable, and provide useful basis for structural design.
