Complex product digital twinning construction and application method based on model fusion

Abstract

The invention provides a complex product digital twinning construction and application method based on model fusion, and relates to the technical field of complex product digital twinning. The digital twinning is formed by fusing an information model, a mechanism model and a domain model, provides evaluation, prediction and optimization twinning application services under the driving of real data, and comprises the following steps: establishing a state information model and extracting a running condition data set according to a running environment and a running process of a physical product; establishing a virtual mapping model according to the structural composition of the physical product; establishing a mechanism model according to the operation rule of the physical product; simulating the operation process of a physical product in a computer system, and extracting state data to establish a twin information model; and evaluating, predicting and optimizing the class domain model, correcting the mechanism model, predicting the behavior and state of the physical product, and optimizing the structure and operation of the physical product. According to the invention, effective twinning construction and application can be carried out in different business activities of products.
