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

<strong>General information on the data set</strong> 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. <strong>Structure of the data</strong> 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) <strong>Allocation of the pages to the sensors</strong> page 1: microphone<br> page 2: acceleration plain bearing<br> page 3: acceleration piston rod<br> page 4: acceleration ball bearing<br> page 5: axial force<br> page 6: pressure<br> page 7: velocity<br> page 8: active current<br> page 9: motor current phase 1<br> page 10: motor current phase 2<br> page 11: motor current phase 3 <strong>Remark</strong> The datasets are not in SI units. For conversion, you can use the PDF documentation. <strong>Further information</strong> 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.
