Abstract

The invention relates to an FMEA analysis method and system. The method comprises the following steps: determining a product structure and a current process route; dividing the devices in the product structure according to the functions of different devices in the product structure; dividing the structure into a virtual part, a black box part or a followed part; according to a product structure and a current process route, respectively determining a function tree of a virtual part and a function tree of a black box part; determining a failure tree of the virtual piece and a failure tree of the black box piece according to the function tree of the virtual piece and the function tree of the black box piece; determining the risk of completing the product according to the current process route and the risk reason according to the failure tree; and returning to the step of determining the product structure and the current process route, and updating the process route. According to the invention, the failure position and reason can be quickly positioned, and the product design efficiency and quality are improved.

Description

technical field [0001] The invention relates to the field of failure analysis, in particular to an FMEA analysis method and system. Background technique [0002] Failure Mode and Effects Analysis is "Potential Failure Mode and Effects Analysis", or FMEA for short. FMEA is to analyze the subsystems and parts that make up the product, and each process that makes up the process one by one in the product design stage and process design stage, find out all potential failure modes, and analyze their possible consequences, so as to take necessary measures in advance. A systematic activity of measures to improve the quality and reliability of a product. [0003] However, due to the complexity and diversity of the product structure, the existing FMEA analysis method cannot quickly locate the location and cause of the failure, and cannot adopt the phenomenon control measures in time, resulting in the quality of the product not meeting the requirements.
