简述了协同仿真平台(COSIM)的体系结构,针对通用仿真程序设计语言开发一体化仿真软件包难以规范和重用的问题,研究了基于COSIM仿真环境的模块化建模方法,通过COSIM的图形化建模工具实现不同粒度的可重用性模型的设计,完成了鱼雷武器的静态和动态行为建模。通过仿真概念推演,验证了所建模型的正确性,并反映了该建模方法具有快捷、规范、重用性好等优点。 In this paper, the architecture of COSIM is briefly introduced. In view of the problem that it is difficult to standardize and reuse the integrated simulation software package of universal simulation programming language, the modeling method of COSIM based on COSIM is studied. Modeling tools to achieve the design of reusable models of different particle sizes, the completion of the torpedo weapons static and dynamic behavior modeling. Through the simulation concept deduction, the correctness of the proposed model is verified, and the advantages of the modeling method, such as fastness, standardization and reusability, are reflected.
