基于模糊理论液压系统故障诊断方法的研究

The Study of the Fuzzy Synthetical Judgment in the Hydraulic Breakdown

通常液压系统的故障诊断大多是根据专家经验来进行的,往往有些故障模糊不清,加上其诊断准确性受专家经验限制,系统故障误诊现象时有发生。本文应用模糊综合评价理论方法错容性好、评价方法简单等特点,对液压系统故障进行智能综合评价,达到可靠、高效评价的目的。

In most case, the ascertainment and process of the hydraulic system breakdown is practiced based on human＇s experience. Applying the fuzzy synthetical method, the author tries to introduce a judgment means of a hydraulic system and a diagnosis of the system breakdown depending on the means, and reach the goal successful- ly on its first process.
