四螺栓铝板在螺栓扭矩变化下的全场激光多普勒振动测量频响函数数据集

中文摘要 AI 辅助

本文构建的数据集基于对一块带有四个螺栓的铝板开展的激光多普勒振动测量实验结果，该数据库捕捉了铝板振动特性随螺栓拧紧扭矩变化的情况。总共有18种不同的拧紧扭矩状态，涵盖从所有螺栓拧紧到所有螺栓松动的情况，其他可能的组合包括仅对一个螺栓施加不同扭矩的状态，以及多个螺栓松动的状态。数据包含从Polytec PSV-500导出的1836个文件，分为振幅数据和相位数据，频率范围为1Hz至51200Hz，间隔为1Hz。对所有扭矩状态，在51个扫描点处分析了识别出的区域。支持文档包括测试板规格、扫描点和扭矩状态信息、选定的共振峰表、七个共振组的测量频率、所有频响函数（FRF）的相关值、可视化结果以及代码脚本。

英文摘要

The dataset described in this article was constructed using the results of laser Doppler vibrometry experiments conducted on an aluminum plate having four bolts. The database captures the variation in the vibration characteristics of the plate as a function of changes in tightening torque on the bolts. In total, there were 18 different states for the tightening torque, ranging from a situation where all bolts are tightened to all bolts being loose. Other possible combinations include states with varying torque applied to just one bolt, and those involving multiple loose bolts. Data consist of 1,836 files exported from Polytec PSV-500, categorized as amplitude and phase data, for frequency ranges spanning 1 Hz to 51,200 Hz at intervals of 1 Hz. The identified zones were analyzed at 51 scan points for all states of torque. Supporting documents included specifications of the test plate, scan point and torque state information, selected resonance peaks tables, measured frequencies for seven resonance groups, correlation values for all FRF, visualizations, and code scripts.
