| Abstract: | To solve the coupling complexity of MDO(multidisciplinary design optimization),coupling factors of a complex system were investigated based on the sensitivity analysis.The conception of coupling strength was presented,the membership degree function of coupling factors was defined with the method of fuzzy mathematics,and the judgment criteria of the coupling degree of coupling factors was given.Based on the conception and the judgment criteria,a decoupling method of MDO was proposed.Finally,a six-bar mechanism was given as an example to demonstrate the validity of the proposed method. |
