Digital Twin and Its Application in Storage and Maintenance of Solid Rocket Motor

Abstract

With the development of the new generation of information technology, the digital twin has become the research hotspot in the field of complex equipment system design and operation and maintenance due to its virtual and real interaction characteristics. This paper summarizes the development of the concept of digital twin, concludes the connotation of digital twin on this basis, and summarizes the current research and application of digital twin. In order to solve the problem that the solid rocket motor's operation, maintenance and life evaluation are not closely combined with the motor entity and specific task requirements, this paper proposes to combine the digital twin technology with the solid rocket motor, discusses the frame structure of the solid rocket motor digital twin body, provides the overall design of solid rocket motor storage performance prediction based on digital twin, and the realization method is described in order to provide reference for the application of digital twin technology in storage maintenance and life evaluation of solid rocket motor.
