汽车车身模具的数字化快速修复技术

针对存在局部物理缺陷或疲劳磨损的汽车车身冲压模具的可重用性,提出了缺陷特征提取和有限元分析耦合技术方案,实现了模具的数字化快速修复。以抽取模具点云中诸如缺陷边界、缺陷原形等特征为基础,并利用特征诱导技术恢复原始模具在缺陷处的基本特征形态。通过冲压过程的动态模拟来矫正基本的特征形态,修复模具在局部缺陷处的CAD模型,为最终以激光焊接技术和高速硬切削技术为基础实现模具的快速物理修复提供可靠的依据。

Towards a holistic digital twin solution for real-time monitoring of aquaculture net cage systems

Digital twins and relevant concepts are being applied in a wide variety of ways, and they are of most use when an actual real-world physical system or process (a physical twin) is changing over time and when measurement data correlated with this change can be captured. In this work, a digital twin model was implemented for real-time monitoring of aquaculture net cage systems, which is notoriously challenging because of several difficult-to-measure properties, such as forces on and deformation of the flexible netting structures, waves and flow field alterations around the cage and complex stiffness behaviour of the mooring elements made by fibre ropes. These properties were set to be adaptable according to the resultant outputs, such as cage responses and mooring loads that were continuously compared with the measurement data obtained from remote monitoring sensors. In this way, real-time sensor data were assimilated into the numerical simulation model for representing the actual net cage system. No dedicated sensors were used for fish monitoring, but the fish behavioural responses to current, wave and cage deformation were modelled according to relevant field observational data. A wireless sensor network has also been tested for the digital twin implementation, which was found to be suitable for practical uses in fish farms.
