摘要
以某型船的蒸汽动力装置主冷凝器水位调节器为研究对象,应用MATLAB软件编译程序,通过计算不同状态下的关联维数,说明其与不同故障之间的关系。实验结果表明,不同故障状态下的信号具有不同的关联维数,因此,分形理论在主冷凝器水位调节器故障诊断过程中的应用是有效可行的。
Based on the research of water lever regulator of steam-power plant＇s main condenser, this paper explains the relation between correlative dimension and different fault by applying MATLAB programs to compute the correlative dimension of different signals. The result proves that different signals have different correlative dimension. Therefore, the fractal theory is an effective method in fault diagnosis of water level regulator of main condenser.
