摘　　要：机械系统的可靠性分析通常采用故障树分析 ( FTA)和失效模式影响及致命度分析 ( FMECA)方法。由于模糊性或不确定性是客观事物的一种本质属性 ,评估系统可靠性的失效模式影响因素也具有模糊性 ,常规分析方法对此很难给出有效而准确的回答。以新型两辊甘蔗压榨机械系统为例 ,讨论失效模式影响模糊评估分析方法的原理 ,评估分析结果可用于创新设计新产品、改造老产品及提高系统的可靠性。Under normal conditions reliability analysis of a mechanical system has Fault Tree Analysis(FTA), Failure Mode Effect and Criticality Analysis (FMECA).Owing to fuzzyness or uncertainty is an essential attribute of objective event, the effective factors which are used to evaluate failure modes of the system reliability also possess fuzzyness, thus, in order to obtain an effective and accurate answer, it is very difficult to do with conventional analysis method. This paper advanced a new method of system reliability analysis i.e. Failure Mode Effect Fuzzy Analysis(FMEFA),and discussed the method of FMEFA with the reliability analysis of new type of Sugar Cane Crusher System for example.
