| Abstract: |
| Aimied at the more uncertainty parameters and nonlinear issues in the complex engineer structure, the response surface for structure was employed between response characters and different variables. In the case of two typical nonlinear indication functions and a screw-connection structure including several uncertain parameters, the response surface model was constructed based on high order exponent polynomial and LS-SVM (Least Squares Support Vector Machine).The modeling procedure using LS-SVM was presented in the paper. Compared with the method of high order exponent polynomial, the high precision response surface can be formed by less samples based on LS-SVM. The more effective result was proved in the high dimension and nonlinear problem of complex engineer structure. |
