Abstract

Abstract: The information about the movement state of the rotary machinery include the static information and the dynamic information，so the diagnostic result about the machinery will be wrong with only the static information or the dynamic information.The information fusion method of the rotary machinery based on the full information is proposed，and the static information and the dynamic information are fused fully，and the fused information can reflect the true movement state of the machinery.Engineering practice indicates that the fusion method is a new and usable method for rotary machinery fault diagnosis.

Key words: full information fusion, rotary machinery, fault diagnosis

摘要： 旋转机械转子运动状态的截面信息包括静态信息和动态信息，仅从静态信息或动态信息分析对转子故障进行诊断可能发生误诊。提出的基于全信息模式的旋转机械信息融合方法，融合了转子的动态信息和静态信息，能真实全面地反映转子运动状态。工程应用实践表明，基于全信息模式的旋转机械信息融合对于旋转机械故障诊断是一种新的、较为实用的信息融合方法。
