摘　　要：本文在已有磁摩擦耗能减振体系振动台试验基础上,讨论了两类磁摩擦耗能减振体系支撑刚度的影响,揭示了支撑刚度对磁摩擦耗能装置减振效果的影响规律,给出了两类磁摩擦耗能装置在结构中发挥最佳减振效果时支撑刚度的取值范围。The shaking table tests , with two kinds of magnet-friction energy dissipation devices on the model structure, have been carried out. The effects of stiffness of bracing member on the permanent magnet-friction energy dissipation system are studied. Based on the numerical results, the rational range of parameters is suggested.
