| Abstract: |
| There are multiple error inputs in simulation and modeling process, which will cause inaccuracy in the simulation prediction resultThe simulation model V&V (Verification and Validation) techniques is used to conduct the simulation and modeling error analysis and control By Using the physical test data, Engineers can evaluate the accuracy of the simulation model, automatically update the simulation and modeling parameters based on the model updating algorithm, improve the consistency between the simulation and the test results This can, help the designers to conduct product virtual performance prediction based on the accurate simulation model, and improve the of the simulation techniques in the product development processThis paper presents the concept and process of model V & V, discusses the key techniques and principles of model V & V in detail, and illustrates how to do model validation with the example of NASA Rotor37 |
