摘　　要：提出了一种新型结构的磁流变阻尼器,该阻尼器主要包括内层缸筒、外层缸筒和线圈组件,其中线圈组件固定于外层缸筒的外侧,电磁线圈不与磁流变液接触,具有装拆方便、容易维护、散热良好、能够提高磁流变阻尼器活塞的有效行程等优点。采用ANSYS软件建立新型结构磁流变阻尼器的电磁场有限元模型,将电磁场理论分析值和有限元分析值进行比较,分析结果表明,外层缸筒和线圈组件的特殊结构,能够保证磁流变液流动通道内产生有效磁场。Abstraet：A new structure of magneto-rheological damper is presented, which mainly includes inner cylinder, outer cylinder and the coil assembly. Coil assembly is fixed at the outside of outer cylinder. Electromagnetic coil is not in touch with magnetic flow. This new structure has such advantages as convenient assembling and disassembling, easy maintaining, good heat dissipation, and improved effective stroke of magneto-rheological damper. Electromagnetic finite element model of magneto-rheological damper is modeled with ANSYS. Compared with the values of the electromagnetic field theory and the values of finite element analysis, analysis from ANSYS confirms that the structure of outer cylinder and the coil assembly enables effective electromagnetic field generated in flow channel of magnetic flow. Key words：magneto-rheological damper; electromagnetic field; finite element analysis
