Abstract

In order to explore the factors affecting the motion state of cultural relics in freestanding collection more effectively, shaking table test and numerical test were used to explore the basic law of the motion state of freestanding cultural relics under unidirectional horizontal excitation. The ceramic vase with a centroid aspect ratio of 3.7 was selected to carry out shaking table tests under unidirectional harmonic and seismic waves, respectively. According to the actual size, a fine finite element model is established and compared with the experimental results, and the excitation acceleration, the friction coefficient of the contact surface and the inclination of the booth surface are parameterized by using the verified finite element model. The results show that the aspect ratio and shape of the specimen, the roughness and inclination of the contact surface, and the frequency and amplitude characteristics of the excitation are all factors affecting the motion state of the freestanding system. The motion state is very sensitive to the friction coefficient. The vase with circular bottom is easy to twist under one-way excitation. in order to ensure the safety of freestanding cultural relics, the level of the exhibition surface should be kept as far as possible.
