基于BESO的产品结构拓扑优化设计方法研究

Research on Product Structure Topology Optimization Design Method Based on BESO

摘要: 本文提供了一种在产品结构设计实践中提高设计效率、结构稳定性的设计流程。产品结构在整个产品设计中扮演着不可替代的重要角色，但是传统的结构设计大都依赖设计者的经验和感觉，缺乏科学性和准确性，导致产品结构性能很难实现最优；同时在产品外观设计(形)与产品结构设计(力)方面也存在矛盾。然而随着计算机辅助设计相关技术的飞速发展，使得更多可能得以实现。本研究以电动行李箱外骨骼结构为例，借助AI绘图工具Disco Diffusion以及拓扑优化BESO对其进行外观结构协同创新设计，通过有限元法验证了该设计流程的有效性。结果表明，该设计流程可以提供更多参考的同时，提高产品结构设计的科学性，实现结构设计过程智能化。

Abstract: This paper provides a design process to improve design efficiency, structural stability, and give designers more reference possibilities in product structure design practice. Product structure plays an irreplaceable and important role in the whole product design, but most of the traditional structural design relies on the designer’s experience and feeling, lacks science and accuracy, so there are various uncertainties in the design process, making the product structure performance difficult to achieve optimization; At the same time, there are also contradictions in product design (shape) and product structure design (force). However, with the rapid development of computer-aided design related technologies, more possibilities have been made. Taking the exoskeleton structure of electric luggage as an example, we design its appearance structure collaboratively and innovatively with the help of AI drawing tool Disco Diffusion and topology optimization BESO. The results show that the design process can provide more references, improve the scientific design of product structure, and realize the intelligent structure design process.
