摘要
为探讨馆藏浮放文物的有效防震措施,采取归类分析方法,研究了基于被动控制技术的馆藏浮放文物隔震装置的开发与应用现状。对国外各类文物隔震装置进行了汇总,探讨了隔震机理,评价了隔震效果,提出了合理化建议。结果表明,与国内相比,文物被动隔震装置的应用在国外博物馆领域相对成熟,滚轴式、滚轮式、滚珠式、滑块式、形状记忆合金式、磁石式、恒力弹簧式、叠层橡胶式等水平隔震装置已相继研发;平行链杆式、负刚度机构式、恒力弹簧式、空气弹簧式、线性导杆式以及扭簧式等竖向隔震装置已逐步应用。对这些隔震装置的合理选择和利用,可达到馆藏文物的隔震目的。此外,新技术的不断运用,使得小型化、高效化的文物隔震装置应用成为发展趋势。
To find effective aseismic measures for museum cultural relics, the development and application of isolation devices for cultural relics based on passive control techniques were studied using classification method. Different types of isolation devices from overseas were discussed, their isolation mechanisms as well as isolation results were analysed and helpful advices were pro- posed. Results show that development and application of passive isolation devices for museum cultural relics in foreign countries are more widely than those at home. On one hand, different types of level vibration isolation devices such as rolling roller, rolling wheel, rolling ball, sliding block, SMA （Shape Memory Alloy）, magnet stone, constant-load spring, laminated rubber and so on have appeared. On the other hand, vertical vibration isolation devices based on parallel links, negative stiffness setups, constant-load springs, air springs, linear guiders, torsion springs and so on have been developed. By rational selection and utilization, these devices can a- chieve well performance. Besides, the development of new technology makes the application of smaller and higher efficiency isolation devices for museum cultural relics possible.
