DFMEA Application In BQ Outside Rearview Mirror Development Process

In the design and manufacture of product,FMEA is an important method for reliability design,it is actually FMA(failure mode analysis)and FEA(Failure Impact Analysis)combination.It possible to evaluate the potential risk analysis,in order to eliminate these risks on the basis of existing technology or reduce these risks to an acceptable level.Automotive exterior mirror system,a complex assembly parts,many border,involving human-computer,electronics,and other professional body,quality control is more difficult,BQ of DFMEA outside rearview mirror application development process is not successful,in the early prevention of homework not done enough,many potential design failure not identified,there is no effective preventive measures,resulting in the product produced,there are still many design issues,these issues to improve waste a lot of manpower,resources,influence product development quality,cost and schedule.This paper will BQ conventional exterior mirrors DFMEA start the application process by analyzing its processes and the use of two aspects,analyze the problem and its shortcomings.External rear-view mirror and failure analysis of the problem raised its corresponding control measures targeted to improve the response to these problems apply to new vehicle development process,and improve BQ outside mirrors DFEMA use,its operation and recycling processes,and these methods and processes used in the new project,and finally,by quantifying the practical application of the results to verify its validity.By focusing on the problem and control the import of optimizing countermeasures DFMEA DFMEA process and its failure to introduce DRBFM key control problems,and achieved good economic models in the new applications,the results can provide a reference for the application of BQ DFMEA other auto parts.
