Abstract

Based on the theory of Kriging, a kind of surrogate model called Kriging response surface is established during the process of model validation for the prediction of response. Primarily, the procedure of model validation is put forward according to the discussion about model verification and validation. Taking the transient response analysis for Garteur benchmark as an example, Kriging response surface for the maximum value of acceleration is established and Monte Carol method is used in order to achieve the positive transfer of uncertainty from model parameters. Also, Kernel density estimation is available to get the probability distribution of the maximum value of acceleration，while the upper bound and lower bound for the response is computed. It is demonstrated that Kriging response surface is able to predict the response of finite element model accurately and is convenient to use for finite element model validation.
