摘要: 研究了斯太尔汽车发动机气缸在不同状态下的关联维数,给出了获得反映其真实状态的关联维数方法。研究结果表明:该发动机气缸振动的时间序列在不同状态下关联维数不同,可以将其关联维数作为识别其状态的特征量,给出了利用分形理论判断斯太尔汽车发动机气缸状态的判椐。

Abstract: The correlation dimension is applied to describe the behavior of STEYR diesel engines. The method for gaining accurate the correlation dimension. The experiment result show that the correlation dimension of vibration signal of the STEYR diesel engines is different for the different state and can be used as characteristics for recognizing the diesel engines fault. The rule for fault diagnoses of STEYR diesel engines is given by using fractal theory.

Key words: Diesel engines, Fault diagnoses, Fractal
