本文在信号相空间重构的基础上 ,求出关联积分 ,然后将关联积分作为一个特征集处理 ,并从中提取诊断特征量 ,进行气门漏气故障诊断。诊断实例表明该方法是可行的 ,并取得了较好的效果
Based on the reconstructed signal phase space, this paper obtains the correlation integral, then treats the correlation integral as a feature set and extracts the diagnostic features from it to diagnose the valve leakage. The diagnostic examples show that this method is feasible and has achieved good results
