Queen's Park Bridge ambient vibration data with multiple setups
收藏资源简介:
Three datasets, TS01, TS02 and TS03. TS01 has 7 triaxial servo acc. 30 min. @ 200Hz for 1 setup, covering 6 locations on one side of bridge and 1 location on the other side, total 7x3=21 dofs. TS02 has 6 (2 reference + 4 rovers) triaxial servo acc. 15 min. @ 200Hz for 16 setups, covering 33 locations each on 2 sides of bridge, total 33x2=66 locations and 66x3=198 dofs. TS03 has 4 MEMS acc. from smartphones for 10 min., covering 4 locations on one side of bridge, total 4x3=12 dofs. The data at different smartphones was started at about the same time but with different sampling rates.
本数据集包含TS01、TS02、TS03三个子数据集。TS01采用7台三轴伺服加速度传感器(triaxial servo accelerometer),单组采样时长30分钟,采样频率200Hz,仅配置1组采样方案;测点覆盖桥梁单侧6个位置与另一侧1个位置,总自由度(degrees of freedom, DOFs)为7×3=21。TS02包含6台三轴伺服加速度传感器(其中2台为参考传感器、4台为移动传感器),单组采样时长15分钟,采样频率200Hz,共配置16组采样方案;测点覆盖桥梁两侧各33个位置,总计66个测点,总自由度为66×3=198。TS03采用4台智能手机内置的MEMS加速度传感器(MEMS accelerometer),单组采样时长10分钟;测点覆盖桥梁单侧4个位置,总自由度为4×3=12。不同智能手机的采样启动时刻大致相同,但各自采样频率存在差异。
