摘要为研究博物馆中最常用的卡固件措施固定馆藏文物的抗震有效性，选取典型的地震易损文物复制品试件（瓷梅瓶与赏瓶），开展文物-抗震系统模型振动台试验，获得不同工况下文物复制品真实地震响应并检验典型卡固件固定措施的抗震有效性。建立相应有限元分析方法，为进一步开展参数分析、补充试验数据、提出科学评判方法提供必要技术手段。结果表明：有限元数值预测与试验结果吻合良好。随着地震波峰值加速度增加，浮放放置方式更易造成文物的震损。同等条件下，文物重心越低，摇摆响应越小，但整体滑移响应增大。卡固件固定措施可有效降低文物的地震响应，但卡固件尺寸增加到一定程度，对文物的抗震固定作用提高有限，基于文物保护中的最小干预原则，综合考虑文物的抗震安全及艺术展示效果,应优化卡固件尺寸。在地震波峰值加速度很大的情况下，卡固件与文物的相互作用易出现应力集中现象，有可能对文物造成局部损伤，需要优化卡固件形式，必要时可在两者接触部位增添硅胶垫层等构造措施。

Abstract：In order to study the seismic effectiveness of the most commonly used fasteners in museums to fix the cultural relics, typical cultural relics specimens were selected, and the shaking table test research on cultural relics- seismic system was carried out to obtain the real seismic responses of cultural relics under different working conditions and to verify the seismic effectiveness of typical fasteners. The corresponding finite element method was established, which provided a necessary technical method for further parametric analysis, supplementary of test data and scientific evaluation method. The results showed that the finite element prediction was in good agreement with the experimental results. As the peak acceleration of seismic waves increased, the floating placement method was more likely to cause damage to cultural relics. In the case of equal conditions, the lower the center of gravity was, the smaller the swing responses were, but the overall slip responses increased. Fixing measures of fasteners can effectively reduce the seismic responses of cultural relics. However, when the size of fasteners increased to a certain extent, the seismic fixation of cultural relics was limited. Based on the principle of minimum intervention in the protection of cultural relics, the sizes of fasteners should be optimized, comprehensively considering the seismic safety and artistic display of cultural relics. In the case of larger peak acceleration of seismic waves, the interaction between fasteners and cultural relics was prone to stress concentration, which may cause local damage to cultural relics. As a result, it is necessary to optimize the form of fasteners, and if necessary, the structural measures should be considered, such as silicone cushion at the contact area.
