摘　　要：为更好地实现博物馆浮放文物的地震安全防护,基于摩擦摆隔震系统的隔震机制,研制了一种浮放文物展柜隔震装置——双向滚轮式隔震装置(Double Roller Isolator,DRI)。制作某博物馆的等比例展柜模型,将研制的隔震装置与展柜组合为一个隔震展柜系统,振动台试验中分别以简谐波和随机波作为展柜隔震系统的外部激励输入,通过试验数据对比分析隔震展柜在不同激励下的输入和输出动力响应。结果表明,研制的浮放文物展柜隔震装置在不同类型和强度的外部激励下均能实现展柜台面地震响应的有效控制,且能够在震后实现装置的自复位,具有良好的隔震性能。To better achieve the seismic safety protection of artistic assets in museums,based on the isolation mechanism of friction pendulum system,a specific intervention of seismic isolation is conceived and realized by double roller isolator(DRI).The model of a museum’s exhibition cabinet was made,the isolation device and the exhibition cabinet were combined into an isolation display cabinet system.Simple harmonic waves and random waves were respectively used as the external excitation input of the isolation display cabinet system in the vibration table test.The input and output dynamic responses of the isolation cabinet under different excitation were analyzed by comparing the test data.The results show that the developed vibration isolation device of the floating cultural relics display cabinet can realize the effective control of the seismic response of the counter surface under the external excitation of different types and intensities,and can realize the self-reset of the device after the earthquake,with good isolation performance.
