基于草绘的机构识别及机构分析方法研究

摘要

In the conceptual design stage,this paper constructed a new design system to support the innovation process,which was of great significance to the design of new products.This paper proposed the concept that considering mechanism constituted as the primitive graphics used in the mechanical design concept sketches,and made a species organization sketch recognition methods for conceptual design.This paper included content data preprocessing of freehand sketch,figure recognition,graphic reconstruction,kinematic analysis.This paper combined the freehand sketches with kinematic recognition technology,analyzed the motion of the mechanism and recognized structure sketch,to realize the evaluation and analysis of sketches mechanism design scheme in the conceptual design.%在概念设计阶段构造新型的支持创新过程的设计系统,对新产品的设计活动具有重要意义.在机械产品概念设计中将机构看成由图元构成的图形,提出一种面向概念设计的机构草图识别及分析方法,主要内容包括手绘草图输入及机构草图识别、机构方案运动分析.把手绘草图识别技术和机构运动相结合,通过对机构草图的识别以及机构的运动分析,实现在概念设计阶段对机构设计方案的评价分析.
