UConn in-house Gearbox Dataset
收藏资源简介:
A two‑stage spur‑gear reducer was instrumented in the Dynamic Systems & Control Laboratory at the University of Connecticut. • Stage 1: 32‑tooth pinion ↔ 80‑tooth gear • Stage 2: 48‑tooth pinion ↔ 64‑tooth gear A 3‑axis PCB accelerometer was mounted on the housing; signals were sampled at 20 kHz through a dSPACE DS1006 board while the shaft ran under constant torque supplied by an adjustable magnetic brake. Shaft speed was logged with a tachometer and used to perform Time‑Synchronous Averaging (TSA) so every record starts at the same angular position, eliminating speed wander. File structure UConn_Gearbox.csv is a plain UTF‑8 CSV with: • 3600 rows – vibration samples per record (≈ 0.18 s at 20 kHz) • 936 columns – individual TSA‑aligned records • columns 1‑104 → class H • columns 105‑208 → class MT • columns 209‑312 → class RC • columns 313‑416 → class SP • columns 417‑520 → class CH5 • columns 521‑624 → class CH4 • columns 625‑728 → class CH3 • columns 729‑832 → class CH2 • columns 833‑936 → class CH1 Thus each class contains 104 records, giving 936 records × 3600 points in total.
美国康涅狄格大学动态系统与控制实验室(Dynamic Systems & Control Laboratory)对二级直齿圆柱齿轮减速器安装了测试仪表并开展测试。 • 第一级传动:32齿小齿轮↔80齿大齿轮 • 第二级传动:48齿小齿轮↔64齿大齿轮 在减速器壳体上安装了三轴PCB加速度计(PCB accelerometer);信号通过dSPACE DS1006板卡以20 kHz的采样率进行采集,此时转轴由可调磁制动器提供恒定转矩运转。采用转速表记录转轴转速,并基于该转速执行时间同步平均(Time-Synchronous Averaging, TSA)处理,使每条振动记录均从同一角位置起始,消除了转速波动的影响。 文件结构 UConn_Gearbox.csv为UTF-8编码的纯CSV文件,其结构如下: • 3600行:单条记录对应的振动采样点数(20 kHz采样率下对应时长约0.18秒) • 936列:单条经TSA对齐的振动记录 • 第1-104列 → 类别H • 第105-208列 → 类别MT • 第209-312列 → 类别RC • 第313-416列 → 类别SP • 第417-520列 → 类别CH5 • 第521-624列 → 类别CH4 • 第625-728列 → 类别CH3 • 第729-832列 → 类别CH2 • 第833-936列 → 类别CH1 由此可知,每个类别包含104条记录,总数据规模为936条记录 × 3600个采样点。
