The concept of Industry 4.0 is defined as a common term for technology and the concept of new digital tools to optimize the manufacturing process. Within this framework of modular smart factories, cyber-physical systems monitor physical processes creating a virtual copy of the physical world and making decentralized decisions. This article presents a review of the literature on virtual methods of computer-aided manufacturing processes. Numerical modeling is used to predict stress and temperature distribution, springback, material flow, and prediction of phase transformations, as well as for determining forming forces and the locations of potential wrinkling and cracking. The scope of the review has been limited to the last ten years, with an emphasis on the current state of knowledge. Intelligent production driven by the concept of Industry 4.0 and the demand for high-quality equipment in the aerospace and automotive industries forces the development of manufacturing techniques to progress towards intelligent manufacturing and ecological production. Multi-scale approaches that tend to move from macro- to micro- parameters become very important in numerical optimization programs. The software requirements for optimizing a fully coupled thermo-mechanical microstructure then increase rapidly. The highly advanced simulation programs based on our knowledge of physical and mechanical phenomena occurring in non-homogeneous materials allow a significant acceleration of the introduction of new products and the optimization of existing processes.

计算机辅助制造过程中的多物理场建模和数值模拟

工业4.0的概念被定义为技术的通用术语,以及用于优化制造过程的新型数字工具的概念。在模块化智能工厂的这一框架内,网络物理系统监视物理过程,从而创建物理世界的虚拟副本并做出分散决策。本文介绍了有关计算机辅助制造过程的虚拟方法的文献。数值建模用于预测应力和温度分布,回弹,材料流动以及相变的预测,以及确定成形力和潜在的皱纹和裂纹的位置。审查的范围限于最近十年,重点是当前的知识状态。以工业理念为驱动的智能生产4。0和航空航天和汽车行业对高质量设备的需求迫使制造技术的发展向智能制造和生态生产迈进。在数值优化程序中,倾向于从宏观参数转换为微观参数的多尺度方法变得非常重要。然后,用于优化完全耦合的热机械微观结构的软件需求迅速增加。基于我们对非均质材料中发生的物理和机械现象的了解,高度先进的仿真程序可以显着加快新产品的推出和现有工艺的优化。
