摘要
博物馆展陈文物出于"展陈美观"等要求主要以浮放为主,在地震作用下存在巨大的安全隐患,现有博物馆展陈文物的防震保护措施主要是各类隔震装置的应用.以某博物馆为例考虑所在场地和建筑物的结构动力特性,确定隔震装置可能受到的地震作用;再分别利用WS-Z30单向小型精密模拟地震振动台和三向六自由度地震模拟振动台,对自主设计并制作的滑动摩擦摆式隔震装置进行振动台试验,通过传导比等参数测试其水平向动力性能和三向地震作用下的隔震效能.
In China, the museum exhibition cultural relics because of the requirements of beautiful exhibition, so they are mainly based on the float.In the earthquake, there is a huge security risk, and the existing Museum exhibition of cultural relics protection measures are mainly used in various types of seismic isolation device.Taking a museum as an example, this paper considers the struc- tural dynamic characteristics of the ground and the building, and the seismic action of the isolation device may be determined. This paper designed and fabricated the sliding fi＇iction pendulum isolation device, respectively using WS-Z30 unidirectional small preci- sion vibration table and three directions, six degrees of freedom shaking table test, Test the horizontal dynamic performance and isolation efficiency through the transmission ratio and other parameters.
