摘　　要：基于最优同调和最优阻尼理论,设计了一种双环串接电磁式混合型动力吸振器;计算了动力吸振器的性能参数,包括电磁力、磁性阻尼和弹簧刚度。在此基础上,以提高动力吸振器力常数,减少漏磁通为目标,在吸振器体积和线圈腔面积不变的情况下,以永磁铁与导磁板厚度比、外永磁铁内径和内永磁铁外径、外导磁板内径和内导磁板外径为变量,对磁场结构进行仿真改进。仿真结果表明,在吸振器磁路结构体积一定时,改进后的动力吸振器的电磁力由102.3 N增加到146.6 N。According to the optimal coherence and optimal damping theory,a double-ring-based electromagnetic hybrid vibration absorber has been designed.The performance parameters including electromagnetic force,magnetic damping and spring stiffness of the dynamic vibration absorber have been theoretically calculated.Accordingly,to improve the force constant and reduce the leakage magnetic flux,the optimized magnetic field structure has been designed in the case of unchanged coil cavity area.Taking the thickness ratio between the permanent magnet and the magnetically conductive plate,the inner diameter of the outer permanent magnet,the outer diameter of the inner permanent magnet,the inner diameter of the outer magnetic conductive plate,and the outer diameter of the inner magnetic conductive plate as variables,the numerical simulation on the electromagnetic field has been conducted.With the same volume,the active control force of the optimized dynamic vibration absorber increases from 102.3 N to 146.6 N.
