| description | In order to improve the accuracy of model updating,the acceleration frequency response function is introduced into the improved response surface model updating.Firstly,the modal participation criterion and the effective independence method are applied to determine the best incentive point and the measuring point; the sample points are selected according to the parameters to be modified; the acceleration frequency response functions of the sample points are calculated; the initial response surface model is constructed.Secondly,the predicted value is tested by using the triple variance criterion; the outliers far from the response surface are eliminated.Thirdly,the initial response surface model is optimized to obtain the optimal solution as a new sample point; the weighted response surface model is constructed by using the ratio weighting method.Then,the finite element model is replaced by the improved response surface model; the objective function is constructed with the minimum of frequency response difference; the modified parameters are solved by cuckoo algorithm.The typical truss structure model is used to verify the effectiveness.The results show that the accuracy and efficiency of the improved response surface model are improved. |
