Vibration data of cantilevered rock model

Experimental models of cantilevered rocks were made using mixed materials. During the experiment, the rock was continuously cut so that the crack depth at the back end of the cantilevered rock was increasing. The direct measurement results in the experiment are the vibration acceleration of the rock in x, y and z directions. This data set contains the acceleration data of the rock before the damage and the spectral data of the vibration acceleration of the rock in eight groups collected during the experiment.本数据集采用混合材料制备了悬臂岩试验模型。试验过程中，通过持续切割悬臂岩试样，使其后端的裂纹深度不断增加。试验直接测量得到的结果为岩石在x、y、z三个方向的振动加速度。本数据集包含岩石破坏前的加速度数据，以及试验过程中采集的八组岩石振动加速度频谱数据。
