摘要
把分形认识论的思想引入到复杂的机械诊断过程。应用分形集合分割原理，对故障模式进行了层次划分，建立了发动机层次知识组织模型。根据分形基元建立了专家系统。通过升降维诊断方法提高了诊断系统的智能性，使诊断结果更具柔性，也使推理诊断过程更接近于专家的思维过程。
Fractal recognition theory is used in complex machine fault diagnosing.Using fractal set cutting principle,the gradation classifying of model is given,and consequently the gradation organization model of engine is obtained.Then by using the basic fractal element,an expert diagnosing system is established.Because of using lift-drop dimension diagnosing method,the diagnosing system is more intellectual;the reasoning process is more like that of expert′s.
