Experimental vibration data collected for a belt drive system under different operating conditions

Dataset is considered as vibration signals of the belt drive system that are collected at different levels of speed and pretension of the belt under different conditions of healthy belt, faulty belt, and the presence of unbalanced weight. The vibration signals are collected from accelerometers attached to the driver and driven pulleys. The collected data includes 17 levels of speed; 400 to 2000 RPM by step of 100; three levels of pretension values, 70, 110, and 150 N, and two levels, according to whether there was the presence or absence of unbalanced weight. The data is from three different operating conditions: normal operation using a healthy belt, unbalanced operation by adding weights that cause imbalance in the system, and anomalous operation from using a faulty belt. Each experiment has been repeated three times, which resulted in 459 runs.

本数据集为带传动系统的振动信号数据集，采集自不同转速与皮带预紧力工况，涵盖健康皮带、故障皮带以及存在不平衡配重的三类运行条件。振动信号由安装在主动带轮与从动带轮上的加速度传感器（accelerometers）采集所得。本次采集的数据涵盖17档转速，范围为400至2000转每分钟（RPM），步长为100；3档皮带预紧力，取值分别为70、110及150牛（N）；以及2档不平衡配重状态，即存在与不存在配重失衡。数据集包含三类运行工况：采用健康皮带的正常运行工况、通过添加配重引发系统失衡的不平衡运行工况，以及使用故障皮带的异常运行工况。所有实验均重复开展三次，最终共获得459组有效运行数据。
