摘要
运用模糊优化理论,建立了具有模糊约束的机械结构优化设计数学模型,结合有限元方法,将含有模糊约束的优化问题转为普通优化来处理.算例结果表明:所采用的模糊优化方法能够体现问题的模糊性和工程结构的实际性.
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.
