摘要针对复合故障多种故障特征相互叠加彼此干扰，给全面准确诊断带来困难，提出了基于复杂网络社团聚类的复合故障特征分离诊断方法。该方法首先应用EMD将复合故障信号分解为若干个IMF分量，由于不同单一故障的特征会在不同频段得以体现，提取每个IMF分量的特征量，建立故障数据网络模型；然后将每个IMF分量视为网络中的社团，根据复杂网络社团结构的特性，进行同类社团合并，合并所得每个社团与单一故障相对应，最后对合并的信号进行分析，实现复合故障特征分离。本文以转子不平衡和轴承内圈、轴承内圈和滚动体复合故障特征分离与诊断为例，验证了该方法的可行性。

Abstract：The diagnosis of composite fault occurred in mechanism is a difficult challenge at present. Due to fault feature of composite failure each other interference, it is hard to composite fault of full and accurate diagnose. This paper presents a diagnosis method that compound fault features separation based on complex network community clustering algorithm. The author firstly do that fault signal is decomposed into several intrinsic mode functions by empirical mode decomposition adaptive. Due to different single fault characteristics will be reflected in different frequency, the author extracts the characteristics of each IMF component and establishes the network model of fault data. We will each intrinsic mode function as the complex network community. According to the characteristics of complex network community structure, we will each intrinsic mode function as the complex network community. Similar community will be merged, which each merge community corresponding different single fault. The last, we will get each community corresponding to different single fault, so as to realize the separation of compound fault. Take the rotor unbalance and bearing inner, bearing inner and bearing roller fault separation characteristics and diagnosis for example, the author proves feasibility of this method.

Key words： complex network community clustering composite fault separation characteristics fault diagnosis
