摘　　要：简要介绍了作者研究开发仿真网格的研究背景,提出了仿真网格的技术内涵、体系结构和目前的实施方案;进而结合近几年的研究进展,较为详细的介绍了阶段性研究成果,包括已完成的仿真网格原型系统Cosim-Grid 1.0v、攻克的部分关键技术和仿真网格Cosim-Grid 1.0v的典型应用示范系统。初步研究与应用表明:(1)提出和开发的仿真网格是一种新型的分布建模与仿真平台,它能克服传统网络化建模与仿真平台在仿真资源动态共享、自组织、协同能力和安全应用机制等方面的局限性,能支持"仿真系统工程"的实施,能扩展分布仿真应用的模式,为协同仿真应用提供新的途径;(2)开发的仿真网格原型系统Cosim-Grid 1.0v在体系结构、门户技术、基于WEB的RTI、服务虚拟化、基于语义的模型资源发现等技术方面有新意;(3)仿真网格是一类具有特色的网格,它拓展了"网格"在具有时、空一致性要求的分布、异构资源(服务)协同工作方面的能力。最后,给出结论和下一步的工作展望。The research and development background of simulation grid was firstly concisely introduced. Then the connotation, architecture and the implementation scheme of simulation grid were proposed. Further more, combined with authors＇ recent research, the phased research achievements of simulation grid were introduced in detail, including completed simulation grid prototype named Cosim-Grid 1.0v, some solved key technologies and typical application demonstration systems on simulation grid. It is shown from the primary practice that： （1） the simulation grid put forward and developed by authors is a new distributed modeling and simulation platform, which can overcome shortcomings of traditional networkitized modeling and simulation platform on dynamical resource share, autonomy, capability of collaboration and security mechanism, can support the implementation of simulation system engineering, and can extend simulation application pattern to provide new method for the collaborative simulation applications; （2）the simulation grid prototype named Cosim-Gridl.Ov has innovation on the technologies of architecture, portals, web-based RTI, resource virtualization, model resource discovery based on semantics, etc.; （3）the simulation grid is a kind of characteristic grids, which expand the collaborative work capacity of distributed and heterogeneous resources（services） with the requirement of the time and space consistency. Finally, the conclusions and further works are given.
