Study on theory of model test in model credibility evaluation

In order to assure the credibility of simulation models used in virtual test, Model Test is one of most import techniques. In this paper, the theory of Model Test in Virtual Test is researched. Firstly, the definition of Test Case is given and techniques of producing test case are researched and presented. Secondly, Evaluation Index System of Model Test and classification of Evaluation Reference are introduced. Thirdly, the Process Model of Model Test is proposed. Finally, researches mentioned above have been applied into the model test of one simulation model of aerodynamic. The practical results showed that all the studies above have important directive to simulation model test in virtual test and effectively assure the credibility of simulation model.
