摘要: 传统设计方法主要考虑产品功能及性能,较少考虑美学等其他因素,难以满足综合要求的提升。为解决这一问题,提出多因素的融合设计方法,实现基于美学、人体工学及性能的智能化融合设计。首先确定多个因素的评价方法,包括依据美学计算原理的多个美学维度的计算公式,以及人体工学和性能的评价公式。结合粗糙层次分析法确定的各因素权重系数,得到多因素的综合评价,建立寻优模型。采用自适应边界的遗传算法求解模型,实现优化设计和创新设计两种模式的设计,最后由 NX10.0 的参数接口生成设计模型,实现智能化的融合设计。通过自行车整体结构的设计案例对所提方法进行检验,得到了明显优化的和具有创新性的设计方案。结果表明,该方法可快速生成满足多因素综合要求的优化方案或若干优质的创新方案,有效解决设计因素单一的问题。

Abstract: Traditional design processes mainly consider functions and performances, without other factors like aesthetics, and are therefore unable to satisfy comprehensive demands. To solve this problem, an automatic multi-factor coupling design method is proposed. Aesthetics, ergonomics and key performances are considered and coupled in an intelligent way. First, based on theory and formula of aesthetic measure, the scores for aesthetic dimensions are calculated. Scores of ergonomic comfort and performance are also calculated from formula. Multi-factor scores are combined with weights calculated by rough hierarchical process, and genetic algorithm with adaptive boundary is utilized to solve the design optimization problem. Optimized design and innovative design are both considered in the process. Finally, the results are transferred into 3D models with NX10.0 integrated parameter interface. The form design of bicycle is used as an example to illustrate the proposed method. According to results, optimized design and multiple innovative designs can be obtained effectively. With this method, product design with multiple factors are realized properly.

Key words: aesthetics, ergonomics, genetic algorithm, multi-factor coupling, optimization design, innovative design
