The constituents of 2D parametric graphics and the associated relations of them are discussed;the key techniques,the building and the driving of the structural constraint and the size constraint model are studied;a efficient method is provided for the serialized design in mining CAD.
讨论了参数化二维图形的组成及其关联关系 ,研究了图形结构约束模型和尺寸约束模型的建立方法和驱动求解等关键技术 ,为开采设计 CAD中系列化产品设计提供了一种有效手段。
Moreover, frozen restraint between the slate and the underneath frozen soil is an important condition for frost heaving of the slate.
另外 ,渠道边坡衬砌层 (板 )和其下冻土层之间冻结约束的存在与否是边坡衬砌层 (板 )会不会受冻胀力的必要条件 ,若此约束存在 ,则可能受冻胀力 ,若此约束不存在(被解除 ) ,则其不可能受冻胀力 。
The new theory and method is based on the study of effective way to transfer and exchange design information between different stage in mechanism design, including definition and classification of Kinematic Chain Unit (KCU), abstracting the commonly Unit Couple Semantics(UCS), foundation of coupling constraints, managing the design information lie in mechanism design and linka.
本文从产品设计基元化和集成化的角度研究机构方案设计中信息传递的有效途径,提出了基于基元联结的机构运动方案进化设计方法,对机构方案设计中的运动链基元的分类、联结语义的提取、联结约束的建立、联结信息的管理及机构运动链的自关联进化等关键技术进行了研究,开发了基元联结的机构运动方案进化设计原型系统,并进行了实例应用验证。
