摘　　要：针对汽车磁流变半主动悬架系统的开发,设计了集供电与减振功能于一体的磁流变减振器。提出了基于准Halbach阵列永磁体的直线发电机结构,并设计了组合隔磁结构,有效降低了磁流变减振器线圈磁场与永磁体磁场的相互干扰,实现了自供电磁流变减振器的集成设计。通过理论与试验研究,探索了自供电磁流变减振器创新设计理论与方法。In the development of automotive MR semi-active suspension system, a MR damper which integrates power supply and vibration damping features is designed. A structure of linear generator based on quasi-Halbach array permanent magnet is proposed, and a combined flux shield mechanism is developed to effectively reduce the mutual interference of magnetic field between the coil of MR damper and permanent magnet, so that the integrated design of self- powered MR damper is achieved. The innovative design theory and method are explored through theoretical and experimental research.
