液压机械臂数字孪生建模方法研究OA

Aiming at the single modeling domain and the difficulty of updating the twin model in the research of Hydraulic Manip-ulator digital twin technology,a hydraulic manipulator digital twin modeling method is proposed based on the theory of digital twin five-dimensional model.The overall digital twin framework containing physical entities,virtual models,twin data,application serv-ices and connections and other modules is constructed,focusing on the virtual model modeling method based on object-oriented,multi-domain unification and incremental modeling ideas,which realizes the function of multi-domain coupling and dynamic upda-ting of the twin model.The experimental results show that the proposed digital twin modeling method for the hydraulic manipulator has high real-time and updatability,which provides a new idea for digital twin modeling of hydraulic machinery.
