Diesel Knock Detection Using Time-Frequency Analysis
-
摘要: 基于分析爆震对柴油机表面振动的影响,给出了用时频分析检测柴油机爆震的方法,代替传统的模式识别方法.实验证明,在时频分布图上可以清楚地分辨所对应的不同的频率响应.Abstract: Joint Time-Frequency Distribution is fit for the analysis of transient and non-stationary signals such as engine surface vibrations.By use of Time-Frequency Analysis,the result of tangible benefits can be obtained on Time-Frequency graphics when detecting knock from the signals generated by these transient phenomena in diesel engines.
