摘要

摘要: 提出了描述空心风扇叶片几何特征的结构设计参数,并由此建立了空心叶片有限元分析模型,同时为适应优化设计的迭代过程,发展了一种能够自动更新空心叶片结构高质量有限元网格的方法.在对简化的设计变量进行合理假设和离散的基础上,将基于强度约束和质量最小化为目标的优化设计问题转化为寻求无约束多目标优化问题,并通过多轮数值正交试验设计的方法获得了空心叶片结构优化设计分析的帕累托最优解.

Abstract: Several structural optimization parameters for the description of the geometric features of a hollow fan blade were determined,then a finite element model was established for the parameterized hollow fan blade.And,a method was developed for automatically updating high-quality finite element grid in hollow fan blade in the iterative process of design optimization.Based on the discrete design parameters already simplified and assumed,the structural design optimization problem for a hollow fan blade based on strength constraint and minimum mass was converted into a multi-objective optimization problem without constraints.Finally,the Pareto optimal solutions were found by numerical orthogonal experimental design method in a several turn.
