自下而上产品设计中的自适应装配建模

自下而上的产品建模方法虽在已有信息化设计资源重用以及设计团队协作等方面比自上而下方法有明显优势,但也存在装配冲突、变型困难等缺点.为此提出柔性组件模型及其自适应装配建模方法.基于标准化、系列化、模块化、合理化等原则.建立了产品各组件的包含选型或变型规则的柔性事物特性表和相应的柔性组件模型.利用这种柔性组件进行自下而上的产品装配建模时,根据组件问的装配要求和柔性组件的选型或变型规则,基于简单冲突消除目标或综合优化目标,自适应地选择或调整相关组件并实现有效的产品装配建模.以某织机机架柔性自适应装配建模为例进行了示范,证明该方法有助于提高设计效率,降低设计成本.

Adaptive assembly modeling in bottom-up product design

Although the bottom-up product modeling methodology has obvious advantages over the top-down modeling as the reuse of the informatization design resources and design teamwork cooperation,it has disadvantages as assembly conflicts and difficulty for design variation.To deal with this problem,the flexible components model and its self-adaptive assembly modeling methodology were proposed.For all the components,based on the principles of standardization,serialization,modularization,rationalization,et al,flexibl...
