基于MATLAB和ANSYS的协同优化设计及应用

Collaborative optimization design and application based on MATLAB and ANSYS

针对常规优化设计方法的不足,提出了一种运用MATLAB和ANSYS的协同优化设计方法。该方法主要包括初始参数设置、单元退化条件、软件自动调用及数据传递。首先设置模型尺寸及材料的力学性能参数,并定义单元的退化条件,再通过MATLAB自动调用ANSYS,使ANSYS后台进行有限元分析,最后以文本的格式存储分析数据,MATLAB和ANSYS可以写入与读取文本文档中的数据。所提出的优化设计方法可以高效、便捷地得出精确的优化结果。以自行车车架及齿啮合式快开门盖优化为例,验证了该方法的可行性和实用性,也为结构优化设计提供了新的思路。

In order to eliminate the defect in the conventional optimization design, the collaborative optimization design based on MATLAB and ANSYS is proposed. It mainly consists of initial parameter setting, unit degradation conditions, software automatic calling, and data transmission. First, the model size and the mechanical properties of the materials are set, and the degradation conditions of the unit are defined. Then, MATLAB automatically calls ANSYS, and ANSYS carries out the finite element analysis at the background. Finally, the data, stored in the text, is written and read by means of MATLAB and AN- SYS. Thanks to the optimization design, the results are obtained in an accurate and efficient manner. The optimization design of bicycle frame and and the gear＇s quick opening cover shows that the method, which is both feasible and practicable, provides a new idea for structural optimization design.
