Embodiment

[0033] A kind of structured DFMEA analysis method of the present embodiment, refer to Figure 1-2 : it is characterized in that, its specific implementation steps are as follows:

[0034] S1: Create a project, and display the product structure of all levels contained in the project in a tree form to form a "product tree";

[0035] S2: Use the "block diagram" and "interface analysis table" to analyze the interface of a single product, and determine the internal interface and external interface of the product;

[0036] S3: Combine all internal interfaces, external interfaces and products to form a "structure tree";

[0037] S4: List and describe all the functions of a single product to form a "function list";

[0038] S5: Identify the relationship between each function and each interface through the method of "functional interface matrix";

[0039] S6: Identify the relationship between the functions of upper-level products and lower-level products, and establish a "function t...

Abstract

The invention relates to the technical field of failure analysis and provides a structured DFMEA analysis method. The method comprises the steps of creating a project; displaying all levels of productstructures contained in the project in a tree form manner to form a product tree; performing interface analysis on a single product by adopting a block diagram and an interface analysis table; and determining an internal interface and an external interface of the product. A structured analysis thought is creatively adopted; functional requirements and failure modes of an upper product and a lowerproduct are effectively sorted and combined skillfully, and finally a high-quality DFMEA report is automatically formed; and the manual filling and sorting time of working staffs is greatly shortened, and the workload is reduced.

Description

technical field [0001] The invention relates to the technical field of failure analysis, in particular to a structured DFMEA analysis method. Background technique [0002] The DFMEA method is a systematic method for quality risk analysis of product design, which allows designers to discover quality risks at an early stage and take appropriate preventive and detection measures to ensure product design quality. For a long time, most engineers have adopted the method of directly filling in the form, which has a heavy workload, and often has problems such as incomplete functions, unclear logic, unclear reasons, and improper measures, which make it difficult to achieve the expected effect of DFMEA application. Contents of the invention [0003] Technical issues resolved [0004] Aiming at the deficiencies of the prior art, the present invention provides a structured DFMEA analysis method, which solves the problem that the prior art adopts the method of directly filling in the ...
