| Abstract: | According to the principle of fuzzy optimization, a mathematical mode of mechanical structure with fuzzy constraints was built, so the fuzzy optimum problem was transformed into the ordinary optimum problem combining with finite element method. An example was given. The result showed that fuzzy optimal method presented in this paper could reflect the problem fuzziness as well as practical engineering structure. |
