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.
Museum exhibits Chen cultural relics out of “exhibition beautiful” and other requirements mainly floats, there is a huge security risk under the action of the earthquake, the existing museum exhibits Chen antiquities shock protection measures are mainly all kinds of isolation devices Application Take a museum as an example to consider the dynamic characteristics of the site and the structure of the building, and to determine the possible seismic action of the isolation device. Then, using the WS-Z30 one-way small precision analog seismic shaking table and three-directional six-degree-of-freedom seismic simulation Shaking table is used to test the shaking table of self-designed sliding friction pendulum vibration isolating device. The horizontal dynamic performance and the isolation performance under three-direction earthquake are tested by the parameters of conduction ratio.
