Research And Implement Of Distributed Cooperative Simulation Platform

In recent years,computer simulation technology plays an important role in the aerospace,biological materials,energy information and other high-tech system development and transportation,business,medicine and other social sciences.However,with the increasing application of real-time system simulation,the scale and structure of the application system are becoming more and more complicated,the simulation requirements are increasing,the geographical distribution of simulation resources is not equal,and the complex system simulation posed a huge challenge,functional single single-phase simulation can no longer be used to solve this kind of simulation problem.In the face of these challenges,the multidisciplinary,multi-field simulation software carry out the distributed collaborative simulation together has become a inevitable trend of development.Distributed co-simulation can not only realize the interoperability of the simulation members in the simulation process,but also improve the efficiency of complex system problems,has a very broad application prospects in the field of simulation.In this paper,the collaborative collaborative simulation software software project as the research background,by the distributed simulation of the technical specifications,the HLA architecture and joint simulation technology combined,based on distributed simulation of advanced standards,designed a distributed Collaborative simulation of the overall framework of the platform,and the entire system was implemented.According to the functional requirements of the whole platform,the platform is divided into four modules: master control module,soft bus module,federated interface module and database module.The first three modules are analyzed and designed in detail.The control module is used as the interface of the platform to complete the control of the global control,such as system management,simulation parameter configuration,simulation process control and model file management.The soft bus module,through the research of RTI specification,And the simplified interface soft terminal Simple_RTI is used to solve the problem of information transmission between the various components of the system.The federated interface module unifies the interface between the various federal members,and realizes the simulation based on Matlab and ADAMS.According to the specific needs of the project,the distributed collaborative simulation platform can complete the simulation process of data and model display,simulation scheduling management.After a series of tests and practical verification,the distributed collaborative simulation platform has the advantages of versatility and scalability,and satisfies the requirements of distributed co-simulation.
