摘要

摘要: 机械结构跨尺度拓扑优化从细观微结构构造和宏观结构布局实现协同设计。受此启发，提出了基于机械结构跨尺度拓扑优化的高校大类招生质量评估量化模型。主要包括：将个体入学成绩、入学报考大类和大类忠诚度按照微结构体分比、特征相关度和性能折减进行量化；基于多尺度有限元和人工神经网络建立微结构等效弹性矩阵表征模型；构建以不同属性微结构在宏观尺度布局为设计变量的跨尺度拓扑优化模型，对整体大类招生质量进行量化评估。在此基础上，对西北工业大学某大类近三年招生质量进行评估，有效优化了学校招生政策。

Abstract: Structural cross-scale topology optimization can realize collaborative design of microstructure and macrostructure, based on which a quantitative model for the enrollment quality assessment is proposed. The main works of the study include: establish the quantification microstructure mapping individual enrollment performance, enrollment category and category loyalty to microstructure volume fraction, feature correlation and performance reduction; construct surrogate model for the equivalent elastic matrix based on artificial neural network and multiscale finite element method (MFEM); construct the cross-scale topology optimization model to evaluate the enrollment quality. Base on the proposed method, the enrollment quality of a certain category of Northwestern Polytechnical University in the past three years is evaluated, which guides the optimization of the college enrollment policy.
