A method and system for establishing an engineering material database

Abstract

The invention discloses a method for establishing an engineering material database according to the digitized standard specification of engineering materials. The method comprises the following steps of: taking the engineering material handbook of each industry as a basis, and obtaining the digitized specification of engineering materials through analysis, conclusion and summarization; carrying out informationization processing on the engineering material handbook to obtain a material table performance parameter data file and correct the obtained table data file; uploading the corrected table data file to a service side to generate a table description file of an XML (Extensive Markup Language) format; automatically parsing the table description file of the XML format to generate a standard XML data model; and automatically storing a material performance parameter value in the XML standard data model into the database. The method has the beneficial effects that a digitized standard specification method of engineering materials is put forward, a digitized tool of a material performance parameter table and a material database construction scheme are developed, and enterprises can be assisted in simply, efficiently and quickly constructing the engineering material database of the own unit at a low cost.

Description

technical field [0001] The present invention relates to the field of engineering materials, and more specifically, to a method and system for establishing an engineering material database. Background technique [0002] Material science is one of the three pillars of society. The reasonable selection and processing of materials directly affects the quality and cost of products. The material information system will play an important role in the research, development, production, promotion, use of materials and the popularization of material science knowledge. important role. [0003] In the whole life cycle of complex product development, the reasonable selection, scientific processing and precise design of materials directly affect the cost and quality of complex products. As an important pillar of CAD / CAE / CAM design, engineering material database plays an increasingly important role in material development, process optimization, physical and chemical testing, product design...

Problems solved by technology

[0007] At present, there are many kinds of engineering material database system software in the domestic market. The main idea is to provide a set of engineering material management system for the enterprise. The enterprise material management personnel are responsible for establishing the enterprise's unique engineering material database, and then the internal design department of the enterprise , strength calculation department, and information technology department. The main features of this system software are: the engineering material database is only a software management system, which does not provide material data, but only provides the functions of adding, deleting, modifying, and checking required for maintaining engineering materials. ;Provide fast search, screening, and comparison functions for engineering materials; the disadvantages are: due to the complexity of engineering material properties, the cost of establishing an engineering material database is huge and the construction period is long, which cannot be afforded by application companies; engineering materials in different industries have different application methods , there are large differences in database storage, organization, and navigation, and these differences often lead to inconvenient use of the system; and there is no simple and convenient digitalization capability of material properties, and the material library cannot be expanded, and new materials that cannot adapt to more technical standards

[0008] The establishment of an engineering material database faces many problems and challenges: there is no unified standard to regulate the management of engineering material data in multiple industries; material data comes from different material tests, and the state of test technology varies greatly; there are many material categories, varieties, and performance attributes. It is complex, and manual maintenance and management are extremely difficult; the material data between industries is hugely different, and it is difficult to unify; and the informatization and digitization of material manuals requires a large workload and high technical requirements
