Using the correlation dimension for vibration fault diagnosis of rolling element bearings .2. Selection of experimental parameters

Determination of the correlation dimension from experimental chaotic time series data involves two steps. First, reconstruction of the attractor using the time delay method from the raw time series, followed by computation of the correlation dimension from the phase space vectors. We demonstrate how this process has been performed experimentally on bearing vibration acceleration time series. The effects on the correlation dimension were noted as each of the relevant parameters was individually varied and the optimum values for each determined. (C) 1996 Academic Press Limited.
