Method and device for defining digital twinborn body by prototype model in unified form

Abstract

The invention relates to a method and a device for defining a digital twinborn body by a prototype model in a unified form, comprising the following steps of: constructing a digital twinborn model ofthe digital twinborn body corresponding to a product prototype model, and mapping the digital twinborn model into characteristics of a corresponding product in the product prototype model; mapping thesimulation action of the digital twinning model corresponding to the digital twinning body into a behavior of a corresponding product at a corresponding moment in the product prototype model; mappingthe original state of the digital twinborn model corresponding to the digital twinborn body into an initial state of a corresponding product in the product prototype model; and mapping a simulation action result of the digital twinborn model corresponding to the digital twinborn body into a termination state of a corresponding product in the prototype model. The prototype model and the corresponding digital twinborn model are mapped, so that composition elements of the digital twinborn body are unified and standardized, the organic combination of objects and behaviors is realized, expandability is strong, and the application is convenient.

Description

Technical field [0001] This application belongs to the field of software simulation technology, and in particular relates to a method and device for defining a digital twin in a unified prototype model. Background technique [0002] The product prototype model is a complex piece of equipment, which itself contains many sub-components, and the characteristics and functions of each sub-component are not the same. The digital models used are different, such as aircraft organism models, engine models, avionics systems, landing gears Models and so on. At the same time, in the entire life cycle, at different points in time, the technical points of interest are also different. Therefore, in industrial enterprises that focus on design and manufacturing, it is necessary to reduce production costs and improve product reliability and availability. Before the product is manufactured and debugged, various possible problems can be eliminated through simulation test. [0003] Digital twin is to ...
