摘　　要：为了满足磁流变液屈服应力测试所需的磁场要求,针对不同的磁源,提出了永磁式、电流励磁式和复合式3种磁路方案。确定了磁路各部分的材料和尺寸参数,并利用有限元软件建模进行仿真计算,分析3种磁路模型的磁感线分布和磁通密度。研究结果表明:复合式磁路更加高效节能,为最优的磁路设计方案。所设计的装置能够满足测试的磁场要求,为后续实验平台的搭建及实验的展开奠定了基础。In order to meet the requirements of the magnetic field required by the yield stress test of magnetorheological fluid,this paper proposed three kinds of magnetic circuit schemes for different magnetic sources,which were permanent magnet type,current exciting mode and compound mode. The material and size parameters of each part of the magnetic circuit were determined. The finite element software was used for modeling and simulation calculation,and the magnetic induction line and the magnetic flux density were analyzed. The results show that the compound magnetic circuit is more efficient and energy saving,which is the optimum design scheme of magnetic circuit. The designed device can meet the test requirement of the magnetic field,which establishes the foundation for the construction of the experimental platform and the development of the experiment.
