摘要
分形理论是研究非线性问题的重要手段。本文介绍了分形理论的基本概念和表征方法,论述了分形理论在粗糙表面表征、磨屑分析、故障诊断、内燃机燃烧过程分析和机械密封寿命预测方面的应用。
Fractal theory is an important means for the study of nonlinear problem.In the course of study,the basic concept and represention of fractal dimension are introduced.At the same time,the state of applications of fractal theory in representation of rough surfaces,grindings analysis,fault diagnosis,combustion procedure analysis of engine and predicting life for mechanical seals are reviewed.
