摘要
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 ,实现气阀漏气故障诊断。诊断实例表明 :该方法是可行的 ,并具有较好的效果。
Based on phase space reconstruction theory,correlation integrals of cylinder head vibration signals were computed out and regarded as feature sets.Some features were extracted from them and used to carry out the diagnosis for valve leakage.The results verified that it is of good feasibility and practicability.
