基于两类可视化方法的柴油机活塞环胶结故障辨识
THE IDENTIFICATION OF RING GUMMING IN DIESEL ENGINE BASED ON TWO KINDS OF VISUAL MEASURES
【摘要】 用两种可视化方法 :二进小波变换图形和浑沌分析中的Poincare截面 ,对采集于柴油机机身的一组振动信号时间序列进行分析 ,以实现故障辨识的便捷性和可视化。
【Abstract】 In the paper,two kinds of visual measures,dyadic wavelet chart and Poincare section,are applied to the fault identification of ring gumming by use of a series of time domain data got from a four_cylinder diesel engine block in diesel engine of high rotary speed and huge power.The results successfully show the good capability of fault identification with the measures suggested.
