Abstract: A digital twin data model driven high-performance virtual simulation method and system, including: based on a product design process, paying attention to variable operating conditions or variable product structures to obtain three kinds of data relevant to a design product, relevant products, or operating conditions: sensor data, mechanism simulation data, and fusion data obtained by correcting the mechanism simulation data with the sensor data; processing the obtained data, reversely resolving a running mechanism according to a data driven algorithm, and building a data model driven high-performance virtual simulation model; and based on new operating conditions of the design product or improved new products, calling the built data model driven high-performance virtual simulation model to obtain the virtual simulation results. The method and system can be used for performance analysis and prediction on design products instead of modeling simulation and physical experiments.
