A new type of display stands has been developed for protecting art objects and artifacts from earthquake damage during severe shaking. The concept of deployable (adaptive) structures has been used for the development in which the following three requirements were taken into account : 1) In normal mode when earthquakes are felt, the stand should not obstruct appreciation of art objects. 2) During earthquakes, they should protect the objects without any damage even in severe shaking. 3) Recovery from earthquake to normal modes should be easily operated by a layman.Performance of the stand was demonstrated by vibration experiments and numerical simulations. The stand is equipped with a sensor and a deployable guard frame which is usually folded under the display stand. When the sensor detects shaking stronger than 60 cm/s/s in acceleration, the frame is triggered to be instantly deployed around the object concerned and prevent it from overturning.

一种新型的展示架已经开发出来，用于保护艺术品和文物在剧烈震动时免受地震破坏。可展开（自适应）结构的概念已被用于开发中，其中考虑到以下三个要求：1）在正常模式下，当地震感觉到，立场不应阻碍艺术品的欣赏。2)在地震时，即使在剧烈摇晃的情况下，也要保护物体不受任何损坏。3)从地震到正常模式的恢复应该很容易由外行操作。振动实验和数值模拟的性能进行了证明。展台配有传感器和可展开的防护架，防护架通常折叠在展台下方。当传感器检测到加速度大于60 cm/s/s的晃动时，防护架会被触发，立即展开到相关物体周围，防止其翻倒。
