本文介绍了DFMEA(Design Failure Mode and Effect Analysis，设计失效模式和效果分析)的概念、目前行业内发动机 DFMEA 的现状及发动机 MBSE(Model Based System Engineering，基于模型的系统工程)。根据MBSE的思路将发动机分成 4 个层级，将层级划分引入FMEA 流程，进行发动机 DFMEA 的开发，整个发动机DFMEA体系分成 4 个层级。以气门系统DFMEA为实例介绍了基于 MBSE 的 DFMEA 建模，根据气门系统的BLOCK图，完成气门系统模型化，在专业模型化工具中搭建气门系统模型。
Development of MBSE Based Engine DFMEA
This paper introduces concept of DFMEA(Design Failure Mode and Effect Analysis),engine DFMEA status in current industry and engine MBSE(Model Based System Engineering).Engine is divided to 4 levels per MBSE idea,induces level dividing to FMEA process,develops engine DFMEA.The whole engine DFMEA structure is divided to 4 levels.Introduces MBSE based DFMEA modelling using example of valvetrain system DFMEA,per BLOCK diagram of valvetrain system completes valvetrain system modelization,establishes valvetrain system model in specialized modelizing tool.
