设计意图捕捉与参数化设计集成研究

Integration of capturing design intent and parametric design

为实现意图捕捉、建模和求解,并且使求解结果可直接作为参数化设计的输入,提出了意图域、载体域和信息域三个概念。从需求的角度分解设计意图,形成意图域;在意图域的指导下,对产品进行结构划分,形成载体域。用意图域映射载体域,形成含有设计信息的信息域。信息域中每个信息单元为一个独立的物理模型,应用优化理论求解模型,得到参数化设计中的主参数。以叉车设计过程为例验证了所提方法的有效性。

In order to capture,model and solve design intent,three domain including intent domain,construction domain and information domain were proposed.The solution to design intent was taken as the input of parametric design system.Intent domain was obtained via decomposing design intent from the perspective of demand,according to its instructions,construction domain was generated by decomposing the structure of product.Then,information domain was produced by mapping the intent domain to the construction domain.The information domain was a kind of physical structure with design information.Each unit in information domain was an independent physical model.It was solved by optimization method and the main parameter in parametric design was obtained.Finally,the forklift design process validated the effectiveness of this method.
