发射车建模与仿真的VV&A应用探索

Prospect of VV&A Application in the Modeling and Simulation of Launch Vehicle

发射车建模与仿真的校核、验证和确认(Verification Validation and Accreditation,VV&A)是建模与仿真过程中保证模型可信度的重要环节,简要论述国内外VV&A的基本概念、研究与应用现状和应用方法。介绍发射车仿真及VV&A应用现状,提出发射车建模与仿真中VV&A的应用方法以及发射车建模与仿真的VV&A应用发展途径。

Verification Validation and Accreditation are very important activities to ensure the credibility of the model in theprocess of modeling and simulation,the widely accepted concept of VV&A is introduced,the research and application level in Chinaand abroad are also discussed in the paper.The application status of VV&A in the modeling and simulation of launch vehicle ispresented,the methods to improve application level and the strategy for development of VV&A in the modeling and simulation oflaunch vehicle are suggested.
