This dataset was constructed by the Institute of Machine Dynamics and Acoustics, Wildau University of Applied Sciences. It systematically recorded full-field laser Doppler vibrometry frequency response functions (FRFs) of a four-bolt aluminum plate under 18 distinct bolt torque conditions. The dataset contains 1836 files, covering displacement-force H1 amplitude and phase data from 51 scanning points, with a frequency range of 1 to 51200 Hz and a frequency resolution of 1 Hz. It also includes post-processing tables such as candidate resonance peaks and tracked frequencies, as well as analysis scripts. The data was collected and exported under free boundary conditions using a Polytec PSV-500 scanning laser vibrometer and an automated impact hammer. This dataset is targeted for research including bolt loosening detection, modal correlation analysis, and damage localization based on FRF shapes in structural health monitoring, aiming to provide high-quality benchmark data for the dynamics of bolted joint structures.
