Sensor data set, electromechanical cylinder at ZeMA testbed (2kHz)

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 HDF5 file as a 3D-matrix
• one row represents one second of the return stroke of one working cycle (6292 rows: 6292 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.
