Background
The material data is important basic information of scientific research and engineering application, and plays a vital role in research, development, production, popularization and use of materials. In the automobile field, the accuracy and reliability of material data directly affect the quality and efficiency of the whole automobile development. For example, the weight reduction of automobiles is required to be performed by optimum design and limit design, and therefore, the performance characteristics of materials need to be accurately grasped in the design stage. Especially, the method has decisive significance for numerical simulation analysis of plate forming and service processes thereof and accurate material characteristic data. With the increasing complexity of engineering and scientific problems and the increasing application of various new materials, the number of material data increases, and how to scientifically and effectively utilize the data and discover valuable information therein becomes an important subject of engineering and academia.
Data informatization is an important approach for scientifically and efficiently applying material data. The method is established on the basis of informatics, and scientific organization, analysis and transmission are carried out on material data by using a computer, a network and the like, so that the extraction, the conversion and the sharing of the material information are realized. The core of data informatization is a database, and various types and scales of material databases are established in the scientific research and industrial fields at present. For example, the national institute of standards has dozens of databases, wherein the material database accounts for a large proportion and covers a mechanical property database, a metal elastic property data center, a corrosion database, a friction and wear database and the like; the metal database SOLMA of the German technical experiment society comprises 3000 ferrous and non-ferrous metal data 2 ten thousand pieces; the units such as British nonferrous metal data center, petrochemical company, iron and steel company, national physical laboratory of metal research institute, Rolls Royce company and the like all establish respective material performance databases. The informatization construction of material data in China is also rapidly developed in recent years. The key projects for data sharing, such as the construction of a national material science data sharing service network developed by the technical department in 2010, are that a national material information traffic network which can meet the requirements of national construction and material science development is established through an Internet platform, so that the sharing of data accumulation application is realized. The automobile lightweight common application data platform is established by the company Limited in China automobile engineering research institute aiming at the automobile development requirement, and plays an important role in the aspects of new material design, material selection, process formulation, material performance prediction, product design, safety evaluation and the like. For steel production enterprises, the database is also a guarantee for improving the core competitiveness of the market.
In recent years, lightweight materials such as high-strength steel and hot forming techniques have been widely used in the automobile industry. Aiming at the whole process of using the automobile plate, the influence of an organization structure, a processing technological process and the like on the forming performance and the service performance of the material needs to be considered comprehensively. Meanwhile, for the application of different types of steel plates on the automobile body, in practice, the search from the automobile parts to the material grade and then to the material performance parameters and the reverse search from the material grade to the typical parts are often required. Conventional material databases do not take these requirements into account and provide corresponding functional modules. In addition, the traditional material database is mainly based on operating systems such as Windows and Unix on a desktop or a workstation and a C/S architecture, and although the data storage capacity is large and the functions are complete, the problems of poor compatibility, weak function expansibility, narrow user plane, high maintenance cost and the like exist. At present, in the field of automobiles, on one hand, the mass material data is continuously increased, and on the other hand, the technical requirements of material selection analysis, forming process analysis, structure CAE analysis, performance evaluation and the like in the development process of the whole automobile and key parts cannot be well met. Under the situation, it is necessary to research and develop an automobile plate data management system with convenient use, good compatibility and wide application range.
Compared with Web webpages and mobile phone APP, a new product 'WeChat applet' developed by Tencent corporation has more advantages, such as low development and maintenance cost and higher running speed, and is the centralized embodiment of the concept of 'light application'. The WeChat applet technology is used for replacing the current mobile terminal native application technology, the problem that the mobile application cannot be compatible with different operating systems is solved, the system development cost is reduced, the complexity of software downloading and installation is avoided, and the system popularization efficiency is improved. Chinese patent "data acquisition management system and method based on wechat applet and application (application No. 201810664851.4)", which discloses a data acquisition management method based on wechat applet, applies information technology and database technology to the field of water source environment information acquisition management, and replaces the traditional manual acquisition management mode by an informationized way, thereby reducing the expenses of manpower, material resources and financial resources, improving the working efficiency of water source environment workers, and enhancing the safety, reliability and sharing of data.
