摘要
借鉴结构工程师的设计经验与直觉判断 ,在一定条件下 ,通过一次有限元分析给出结构的传力路线 ,并由此确定拓扑结构 ,利用MATLAB优化工具箱进行形状与尺寸的优化 ,以达到结构优化设计之目的。算例结果表明 :本文方法思路简单、力学概念明确、算法简洁有效 ,易于被结构工程设计人员所接受。
Benefiting from design experience and intuitive judgment of structural engineer, on a certain condition, the authors give one kind of force transfer path through a time FEM analysis. The structural layout is determined by the chart of force-flow. In order to acquire structural optimal design, the MATLAB optimization tool-box is used to get the optimum on shape and size optimization. The examples express that the proposed method, which is easy prone to accept by structural designer, is definitude on mechanics concept, and its algorithm is not only concise but also effective.
