| 摘 要： | 有限元方法与最优化方法是工程设计与分析的两个常用方法,将两者结合起来,可以很好地实现楔环连接结构的多目标优化设计.基于响应面法确定楔环连接结构的4个几何参数的各种组合样本,利用有限元分析软件ANSYS时不同参数组合样本的楔环连接结构进行应力场分析,然后以既降低结构最大应力又减轻结构质量为目标,通过MAT-LAB中的多目标优化设计工具计算得到楔环连接结构的4个几何参数的最优值.数值计算结果表明,优化几何参数后的楔环连接结构比原结构最大应力下降13.6%,质量下降12.5%.

| Abstract: | The finite element method and the optimization method are two methods usually used in the engineering design and analysis.Let the both methods be banded together could nicely achieve the multi-objective optimization design for the wedged-ring linking structures.Various kinds of combined specimens of 4 geometric parameters were ascertained for the wedged-ring linking structure based on the response surface method.The stress field analysis was carried out on the wedged-ring linking structure of different para... |
