摘要：为快速诊断出液压挖掘机产生的故障原因，构建了液压挖掘机故障诊断的模糊数学模型.通过经验数据隶属度矩阵和专家优序数隶属度矩阵计算出故障诊断原因向量，由最大隶属度原则得到最终故障原因.将此方法运用于SWE50型挖掘机液压系统故障中，顺利找出故障原因是液压泵磨损，泵油压力偏低.

Abstract: For rapid diagnosis of the fault cause of hydraulic excavator,this article,based on the fuzzy mathematical model,presents a new fault diagnosis method.This method first gets vector of fault diagnosis by means of the combination of membership degree matrix through experience data and the expert optimal ordinal membership degree matrix,and then uses the maximum membership degree principle to get the final cause of the problem.The fault cause of hydraulic excavator SWE50 (hydraulic pump wear and lower pump oil pressure) is successfully diagnosed by this method.
Key words: hydraulic excavator, fault diagnosis, fuzzy mathematics, membership matrix
