摘要
The digital twin of mechanical products is a dynamic mapping developed by multiple stakeholders in the entire lifecycle,and the synchronization of its model evolution has become an important technical problem that needs to be solved urgently.Considering the multi-source heterogeneous evolution content and the trust-variable collaboration background,a blockchain-based collaborative evolution method for the digital twin ontology model of mechanical products was proposed.The evolution information was converted into standard exchangeable data through ontology-based representation and encapsulation technology.On this basis,the block structure was designed,and the consensus algorithm was used to realize the synchronous update of the model at each node in the authorized network.Through blockchain-based distributed storage,the modeling operations were mutually trusted and traceable.In this method,conflict identification and lightweight publishing were also supported.The evolution process of a clutch in the helicopter was taken as an example to verify the feasibility and effect of the proposed method. © 2023 CIMS.
