Sensor data set of 3 electromechanical cylinder at ZeMA testbed (2kHz)
Creators
Description
General information on the data set
The data set was generated at the ZeMA testbed. A working cycle lasts 2.8s and consists of a forward stroke, a waiting time and a return stroke. The data set does not consist of the entire working cycles. Only one second of the return stroke of each working cycle is used.
Structure of the data
- data saved in three HDF5 file as a 3D-matrix, one file is for one axis
- one row represents one second of the return stroke of one working cycle
axis 3: 6292 cycles
axis 5: 6083 cycles
axis 7: 5732 cycles - one column represents one datapoint of the cycle, that is resampled to 2 kHz (2000 columns)
- one page represent one sensor (11 pages: 11 sensors)
Allocation of the pages to the sensors
page 1: microphone
page 2: acceleration plain bearing
page 3: acceleration piston rod
page 4: acceleration ball bearing
page 5: axial force
page 6: pressure
page 7: velocity
page 8: active current
page 9: motor current phase 1
page 10: motor current phase 2
page 11: motor current phase 3
Remark
The datasets are not in SI units. For conversion, you can use the PDF documentation.
Further information
For an introduction and tutorial to this data, a set of Jupyter notebooks is available here. These notebooks contain Python code and a documentation of example machine learning tasks and analysis of this data set. In the near future, these will be extended to also include uncertainties in the input data.
