Abstract: While evaluating damage efficiency, it is especially important to deduce the damage response function, which is mainly achieved by deduction from a variety of experiments. In order to get a valid damage response function on condition of a very limited number of prototype experiments, on the one hand, a dimensional method is used to exploit the information hidden in the physical model, and the reduced scale experiment is involved to develop the experiment technology; on the other hand, a parameter model based on the discrepancy between the reduced scale model and the prototype experiments is constructed, and then a fusion model is also constructed. Based on all of the work above, an integrative optimal design of the two kinds of experiments is developed to increase the efficiency of the experiments. Examples about the construction of a parameter model of the discrepancy and an integrative optimal design of experiments are given to show the superiority of the proposed method.
