提出了一种基于巴克豪森噪声混沌吸引子的钢板疲劳评价方法。磁性材料的疲劳和退化影响磁畴。因此，这些可以用巴克豪森噪声来评估。磁性材料的巴克豪森噪声是一种非常复杂的波。因此，我们需要一种特殊的评价方法来使用它。疲劳应力试验后巴克豪森噪声的定量变化可以通过测量巴克豪森噪声所构造的混沌吸引子的分形维数来确定。
This paper presents a fatigue evaluation of steel plates based on chaotic attractors of Barkhausen noise. The fatigue and degradation of magnetic materials affect the magnetic domain. Hence these can be evaluated by Barkhausen noise. Barkhausen noise from magnetic materials is a very complicated wave. Thus we need a special evaluation method to use it. The quantitative change of Barkhausen noise after a fatigue stress test can be found by the fractal dimension of the chaotic attractors constructed by the measured Barkhausen noise.
