摘　　要：以双线圈内绕型剪切阀式磁流变阻尼器为研究对象,根据其磁场自封闭性,采用磁路法建立磁路数学模型。通过关键结构参数进行定性分析,得到活塞台阶间隙处磁感应强度近似化的结构优化依据。利用Ansoft Maxwell有限元仿真软件进行验证,结果表明:对于双线圈甚至多级线圈的内绕型剪切阀式磁流变阻尼器,采用磁路法进行初期设计计算有效且精确。With double circle around shear valve-type magnetorheological damper as the research object,according to the internal self-closed property of the magnetic field,the magnetic circuit mathematical model was established by using magnetic circuit method.Through the qualitative analysis on the key structural parameters,the structure optimization basis of magnetic induction intensity approximation at piston bench clearance was obtained.Ansoft Maxwell finite element simulation software was used for verification.The results show that the magnetic circuit method is effective and accurate for the initial design and calculation of the double-coil or even multi-coil shear valve-type magnetorheological damper.
