This data set contains both normal and failure datasets of metro bogies. We collected X, Y and Z axis vibration acceleration data of bogies at a sampling frequency of 1024. The data set includes about 50.8 minutes of normal data and 101.4 minutes of failure data.
Two energy harvesting sensor nodes was used to collect the vibration acceleration data from two metro bogies. One bogie is in normal state and the other is in a failure state. A 3-axis accelerometer is used in each sensor node to collect 3-axis vibration acceleration data. The normal dataset is in the Normal folder. And the failure dataset is in Failure folder.

We will continue to collect vibration data and public the dataset in this open source project to help more research. The vibration acceleration dataset for the complete life cycle of bogies will be provided in the future.
