基于AFD的失效原因分析技术研究

Research of the Failure Cause Analysis Method Based on AFD

预期失效分析(Anticipatory Failure Determination,AFD)是通过反向思维将失效问题转化为发明问题的一种失效分析方法。AFD即可应用于产品设计中的失效预测分析。也可应用于失效原因诊断。提出了集成TRIZ冲突解决原理及AFD的失效原因分析方法,分析了一个应用该方法进行失效原因诊断的实例。

AFD（ Anticipatory Failure Determination） is a kind of failure analysis method which translates the failure analysis problem into inventive problem by reversed thinking, it can be used to failure prediction and failure cause analysis. The theory of AFD and the failure cause analysis method which utilize AFD and TRIZ contradiction theory is introduced, and an example is analyzed by this method.
