Workshop 4- Failure Mode and Effect Analysis (FMEA) Document Review

Speaker I Mike, Dai

Editor I Wilson, Hu

Posting time: Mar. 20 2024

This FMEA workshop once again invited senior Dai Shangzhi (Azhi) to share tools for assessing failure modes and effects. What is the purpose of FMEA? How should the file be written? What should we pay attention to when reviewing FST? In addition to serving as a review document for the league, FMEA is also an important key for the team to carefully consider how to monitor potential problems and prevent errors during the car building process.

Introduction to FMEA

  • FMEA refers to Failure Mode and Effects Analysis, which is a risk assessment tool used to prevent future errors and reliability failures.

  • FMEA is a cyclical process, with content and values constantly updated. What are the risks of including a failure? Is there any way to monitor it? What has the team done to reduce the chance of failure?

  • During the development process, you should not only think about functions when designing, but ignore the possibility of failure.

File content and format

  • The FMEA architecture includes several steps, such as structural analysis, functional analysis, failure analysis, DFMEA risk analysis, and DFMEA optimization. In addition to focusing on the elements themselves, it is also necessary to consider the functional requirements and characteristics of the upper and lower level elements.

  • Failure severity and detection capabilities are also part of the FMEA.

FST version of FMEA and review

  • FST provides 14 examples of filling in items

  • In view of the fact that teams participating in the past have encountered more or less problems related to battery packs, the FST version of FMEA focuses more on the battery pack part.

  • The review focuses on monitoring failure modes and how to prevent their occurrence at the design stage, and pragmatically reflects the design status of the vehicle.
