Abstract
The present invention relates to the field of digital twin technology, in particular to a fiber metal laminate hydroforming system based on digital twin technology, including a database module, a real-time data transmission module, an analysis and prediction module, an optimization module, an adjustment module and a self-learning module; The database module, analysis and prediction module, optimization module and self-learning module form a digital twin. The database module includes the physical data of the fiber metal laminate, the physical model obtained from the forming experiment and the working parameters of the hydroforming equipment; the real-time data transmission module can exchange data in real time; the analysis and prediction module, the optimization module and the adjustment module pass The working parameters of the hydraulic press are adjusted in real time by analyzing and predicting the state of the laminate; the self-learning module can summarize the forming data and import it into the database. The system of the invention guarantees the forming quality and effectively reduces the forming difficulty by precisely controlling the working parameters of the hydroforming equipment.
Description
technical field [0001] The invention relates to the field of digital twin technology, in particular to a fiber metal laminate hydroforming system based on the digital twin technology. Background technique [0002] Fiber Metal Laminates (FMLs) is a kind of super-hybrid composite material obtained by alternately laying metal sheets and fiber-reinforced resin prepregs after specific interface treatment and curing under specific temperature and pressure. Metal materials have the advantages of good processability, strong impact resistance, and high fatigue strength of fiber-reinforced composite materials, as well as good damage tolerance performance. Fiber metal laminates have many desirable properties such as high specific strength, high specific modulus, good fatigue performance, wear resistance, vibration reduction, high electrical conductivity, dimensional stability, and no moisture absorption. new composite materials. [0003] The hydroforming method of fiber metal laminat...
