Reliability of the models and processes becomes the important concern for researchers, with abroad application of the simulation technique. Based on the VV&A of simulation models, some common used methods of effectiveness assessment for simulation models and their application in special vehicle simulations were introduced such as finite element model of pressure vessels, mechanical-electrical-hydraulic coupling models and multi-body dynamic model of full vehicle, etc. The model correctness and accuracy was assessed, the applicability of the effectiveness assessment methods was proved, which set important foundations for the follow-up significance analysis and model updating.
