Embodiment Construction

[0038] When an enterprise builds a reliability data model for its product line, the present invention provides a fault-centered, evolutionary reliability data modeling method. The implementation process can be divided into four stages based on the reliability engineering requirements of the enterprise. steps, such as figure 1 shown.

[0039] A kind of complex product reliability data modeling method of the present invention, its specific implementation steps are as follows:

[0040] Step 1. Sort out the existing product lines of the enterprise, classify them hierarchically according to various products of the enterprise and their components, organize products according to product families and product instances, establish the relationship between product families and product instances, and clarify The design discipline to which the product family belongs, and divide the product family into different design disciplines. A design specialty corresponds to one or more product fam...

Abstract

The invention relates to a reliable data modeling method for complex products, which comprises the following steps of: 1, classifying and integrating the conventional data in enterprises, and establishing a multi-view hierarchical product data model of 'specialty-product family-product instance-function-life profile'; 2, analyzing reasons which influence the reliability of the products systematically to find internal and external factors which influence the reliability of the products possibly, and providing an influence factor of each factor according to specialist experience to find the key influence factors and data items thereof; 3, establishing the mapping relation between the multi-view hierarchical product data model established in the step 1 and a product failure data entity and between a reliable influence factor data model established in the step 2 and the product failure data entity respectively, and establishing a semantic model of 'multi-view product-reliable influence factor-reliable design activity' simultaneously by establishing the relevant relation between a reliable design analytical method and the entity; and 4, implementing a reliable data model on a product data management (PDM) system, and providing an object model for succeeding to the PDM system so as to realize the method and steps of the reliable data model on the PDM system.

Description

Technical field [0001] The invention provides a reliability data modeling method for complex products, which relates to a reliability data modeling method suitable for the whole process of complex product development, used to support reliability index demonstration and reliability design in the whole process of complex product development Analysis, reliability test evaluation and reliability production assurance, etc., and provides a method to realize the reliability data model in the product data management (PDM) system. It belongs to the technical field of system reliability. Background technique [0002] In the development of complex products (such as aerospace products, automobiles, etc.), the reliability problem has gradually become an important problem to be solved by complex products. Reliability work runs through the entire development process, from proof of concept to mass production. However, due to the fact that traditional reliability technology is mainly based...
