复杂机电产品基于元动作分解的可靠性建模及故障诊断
Reliability modeling and fault diagnosing method of complex electromechanical products based on meta-action decomposition
摘要
Abstract
To study the fault diagnosis method of many-movement complex electromechanical products,we first decomposed complex electromechanical products according to functions-movement-action (FMA) structural decomposition and established a reliability and fault diagnosis model based on meta-action decomposition and signed directed graph.Then,to improve the ability of fault identification,we brought the meta-action quantitative information of complex electromechanical products into the reliability and fault diagnosis model and diagnosed the fault of meta-action quantitatively by fuzzy theory.The proposed method can improve the fault identification ability of products by monitoring the operating status variables,and provide a fundamental model for fault root cause analysis.Finally,certain machining center was taken as an example to verify the effectiveness of proposed model and analysis method.关键词
