It was proposed that a model-based digital twin modeling method for complex equipment to address the prob-lems of complex interdisciplinary situations,diverse equipment models,difficulty in data integration and so on during the development of complex equipment.First,based on the analysis of equipment digital twins,and combined with the thinking of system engineering,a model-based complex equipment digital twin modeling framework was proposed.Secondly,ac-cording to the digital twin forward design V model of"design-implementation-verification",conduct modeling and analysis of the digital twin around the dimensions of requirements,functions,logic,physical architecture,etc.,we obtained a digit-al twin design plan that has been verified in advance.We extracted the design data required for heterogeneous models in the design plan,and used professional modeling tools to carry out digital twin modeling and design.Finally,we took artillery research and development as an example to verify the feasibility of this solution.
