摘　　要：电涡流阻尼非常适用于微幅减振运动,采用瞬态磁场的分析方法,比较几种情况下的阻尼系数,结果表明,采用Halbach磁体阵列单侧增强性,可以增大单侧的磁场强度,从而大幅度提高电涡流阻尼的耗能能力。Eddy current damping is highly suitable for micro-amplitude vibration damping.The damping coefficients in several cases are compared by using the transient magnetic field analysis method,the one-side magnetic field intensity can be increased,and the energy dissipation capacity of eddy current damping can be greatly increased.

关 键 词：电涡流阻尼 比较 耗能 HALBACH阵列
