混沌分形对揭示事物的非线性本质具有独特性,基于混沌分形的方法对复杂机械系统的早期故障较为敏感.将混沌分形用于复杂机械故障诊断中,用关联维来刻画故障特征,在旋转机械的滚动轴承故障诊断中取得了较好的效果.
Chaos and fractal theory has its particular characteristic in posting essences of things, methods based on chaos and fractal theory is sensitive to complex machine system forepart faults. So chaos and fractals theory is used to complex machine fault diagnosis with correlation dimension representing fault characteristics. Good results are obtained for roiling bearing fault diagnosis in rotating machinery.
