摘要

机电系统中的组件和组件族经常表现出与系统环境无关的故障特征，并且在不同应用中可重复出现。在本文中，我们展示了为系统安全分析的目的捕获和重用这些模式是可能的。我们描述了一种能够表达失败行为的语言，并描述了这种语言中的一些有用的模式。本文展示了故障模式的仔细重用与自动化故障树、故障模式和影响分析工具的结合如何有助于简化复杂的安全评估。

A Language for Failure Patterns and Application in Safety Analysis

Components and families of components in mechatronic systems often exhibit failure characteristics that are independent of system context and repeatable across applications. In this paper, we show that it is possible to capture and reuse such patterns for the purposes of system safety analysis. We describe a language that enables expression of failure behaviour and describe a number of useful patterns in this language. The paper shows how careful reuse of failure patterns in conjunction with a tool that automates Fault Tree and Failure Modes and Effects Analysis can help to simplify complex safety assessments.
