| Complex system equipment such as missiles,armored car,multiple rockets,and fighters are the core components of the three-dimensional offensive and defensive force in the framework of the equipment system,and will surely play an important role in the future combat system.The independent research and development of weapon equipment system in China started relatively late.From the beginning,they were “imitate first,then test fire” imitations based on foreign advanced weapons through reverse design.Through the efforts of several generations of scientific researchers,China is developing in the direction of positive design.At present,China has the ability to independently research and develop new weapons,and is also staying ahead in the research and development capabilities of tanks and missiles in the world.With the new round of technological development and industrial transformation,weapons and equipment are developing in the direction of informatization,precision,intelligence,high penetration,high damage,and high cost efficiency.This also leads to the traditional document based weapon system design method can not support the development of weapon system with increasingly complex functions.In order to solve the problems of low integration in the traditional design of new complex weapon system equipment and unable to realize multidisciplinary optimization design,this paper introduces the Model-based Systems Engineering(MBSE)method into the design process of weapon system.This paper uses the MBSE method to analyze complex system equipment and conduct demand analysis,and systematically model each independent sub-system,taking the system model as the core of the design,and the system design of complex system equipment is realized through continuous verification,modification and iteration of the model.Model-based systems engineering has the advantages of system design integration,unambiguous knowledge expression and model reusability,and can make up for a series of problems that traditional document-based system engineering brings with the increase of system complexity.Based on model-driven system engineering,this paper studies the application of OOSEM methodology and Sys ML modeling language in the design of complex system equipment.By defining the state and function representation method,the foundation of system model is established to support function decomposition,so as to simplify the design,modeling and analysis of complex system equipment architecture.By introducing virtual prototype and drawing on its all-digital design concept,this paper proposes a model-driven,virtual-real fusion design method for complex system equipment.The process of "design-test-verification" is completely simulated by computer,so as to greatly reduce the research period and cost of complex system equipment.Meanwhile,in order to improve the visualization,participation and credibility of the design process,this paper introduces Virtual Reality technology,uses UE4 virtual engine to construct a virtual real mapping model co simulation architecture for complex system equipment,realizes the drive of system model to virtual model,and verifies the performance of the design system through virtual real model co simulation.In this paper,a modelbased missile system design platform is designed and developed based on the vehicle missile system of complex system equipment,and the feasibility of the method is verified. |
