基于数字线索和数字孪生的生产生命周期研究

摘要

新一代信息技术在制造业中深度应用,引发传统产品研发模式的变革.介绍了利用数字线索和数字孪生开展复杂产品生命周期业务过程建模与仿真、动态预测和评估,实现数字空间与物理空间虚实映射的产品规划与定义、模拟与分析、验证与确认的业务闭环.最后结合航空工业智能制造架构,给出在生产生命周期中的应用思路,以提升生产过程的数字化与智能化水平.%With the deep application of new generation information technology in industry,traditional product re-search and development mode has changed. This paper introduces the modeling and simulation, dynamically predicts and estimates complex product lifecycle business process by using digital clues and digital twin, to achieve the business closed-loop mapping of digital space and physical space of the product planning and deifnition, simulation and analysis, veriifca-tion and conifrmation. At last, combined with the smart manufacturing framework of aviation industry, the application idea in the production lifecycle is given to enhance the digital and intelligent level of the production process.
