Data for Structural Damage Identification Research

The data support the research titled "Structural Damage Identification Using Single-Point Vibration Data Processing." In this study, an efficient nonlinear analysis framework is employed to compute the dynamic response of a cantilever beam with a crack. Spectrograms of the tip response under various combinations of crack parameters are then generated using the short-time Fourier transform. These spectrogram samples are subsequently used to train a convolutional neural network for structural damage identification. The data are provided in MATLAB-compatible .m files.本数据集支撑题为《基于单点振动数据处理的结构损伤识别》的研究。本研究采用高效非线性分析框架，对含裂纹悬臂梁的动力响应进行计算。随后通过短时傅里叶变换（short-time Fourier transform）生成不同裂纹参数组合下悬臂梁端部响应的语谱图。这些语谱图样本随后被用于训练卷积神经网络，以实现结构损伤识别。本数据集以兼容MATLAB的.m文件格式提供。
