【摘要】 生长型设计是把生物生长的机理用于产品概念结构设计的方法。首先介绍生长型设计的基础理论,从而提出基于功能表面的产品生长型设计方法,论述生长型设计的主要步骤。提出功能表面分解时遵循的原则,即在满足功能需求的前提下,实现装配复杂度和制造复杂度最优分配。提出基于匹配度的概念产品向实体产品的映射方法。给出具体实例,生长型设计方法的有效性得到验证,该方法可以部分实现概念设计的自动化,基于功能表面的概念设计结构模型可以应用于后续的详细设计。更多还原

【Abstract】 Growth design is proposed for mechanical structure design by using the growth methodology of organism.The theoretical foundation for the growth design is introduced firstly.The process of growth design is presented based on the decomposition of function surface,and the main growth step is introduced.For the purpose to meet the functional requirements,the optimal allocation of assembly complexity and manufacture complexity is used as the principle for the decomposition of function surface.The matching degree is proposed for the mapping between conceptual parts and entity parts.Finally,an example is given to demonstrate the effectiveness of the design theory.Concept design automation can be achieved partially by using this method.The concept structure model based on function surface can be applied to the following detailed design.更多还原
