下游活动 meaning in English
downstream activities
Examples
- Besides expressing design result , it provides domain constraint for design process and model information for digital assembly sequence planning and simulation of stamping die , which is usually ignored in the former product models . taking the specific structure and design process of stamping die into account , the information of workpiece is composed in die product model as product feature . former product models merely contain mainly about the die design result , this model extends the contents of product model with the relation feature of the composed subassembly and parts and also other associated production knowledge
该模型不但能完整地表达冲模的设计结果，同时还表达和存储了冲模设计的知识信息，能较好地为冲模的设计过程提供规则和约束，支持产品的智能设计过程以及冲模的数字化预装配规划和仿真；而模型中冲压件信息的集成则扩大了冲模产品模型的信息内涵和应用外延，便于建立冲模智能设计过程的信息关联，从而使集成信息模型成为产品设计过程上、下游活动实现信息共享的基础。
