摘要从实验混沌时间序列数据中确定关联维数包括两个步骤。首先，使用时间延迟方法从原始时间序列重建吸引子，然后从相空间向量计算关联维数。我们演示了如何在轴承振动加速度时间序列上进行实验。由于每个相关参数单独变化，并确定了每个参数的最佳值，因此记录了对相关维数的影响。
Abstract 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 times 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.
