摘要
为了满足下肢康复外骨骼造型美观化与结构轻量化的双重要求,提出一种造型设计与结构优化互补的综合设计方法。运用感性工学理论和设计美学原则,归纳出下肢康复外骨骼造型设计的一般特征,并应用于下肢康复外骨骼的造型设计中,然后采用7点标度的语义差异量表挑选造型方案。为了验证造型方案结构的合理性,利用SolidWorks软件对优选方案进行三维建模和有限元分析,同时在不改变优选方案造型轮廓美观性的基础上,使用拓扑优化方法对其进行轻量化设计。最终设计得到的造型方案不论是在造型美观性方面还是结构性能方面都比较突出,表明了该方法的有效性。
In order to meet the dual requirements of the aesthetics of the lower extremity rehabilitation exoskeleton and the lightweight structure, a comprehensive design method of modeling design and structural optimization is proposed. Using the principles of kansei engineering and design aesthetics, the general characteristics of lower extremity rehabilitation exoskeleton design are summarized and applied to the design of lower extremity rehabilitation exoskeleton. Then the 7-point scale semantic differential scale is used to select the modeling scheme. In order to verify the rationality of the structure of the modeling scheme, the SolidWorks software is used to carry out the three-dimensional modeling and finite element analysis of the preferred scheme and on the basis of not changing the aesthetics of the contour of the preferred scheme, the topology optimization method is used to reduce the exoskeleton weight.The final design of the design scheme is outstanding in terms of aesthetic appearance and structural performance, indicating the effectiveness of the method.
