并行工程中的集成装配结构设计

以微波产品的装配结构设计为例描述面向并行工程的装配结构设计系统 ,该系统读取由产品数据管理 (PDM)传过来的上游设计部门的设计要求 ,以基于实例的方法产生装配方案 ,同时将设计要求分配到各个组成零部件中 ,在设计约束下对零部件进行详细设计 ,并将最终的设计结果按照不同部门的需要 ,通过PDM系统分别向上反馈 ,向下传递 ,从而实现信息的集成与共享 ,达到实现并行设计的目的 .

Integrated Assembly Structure Design Within Concurrent Engineering

Taking a microwave product as an example, a system of integrated assembly structure design is presented. Getting design constraints from the upstream design section through product data management(PDM), the system generates the assembly scheme using the case? based method, then assigns the design requirements into each component of the assembly. The detail design for each component can be performed under these design constraints. In order to practise concurrent design, the system sends the final design result to the upstream section and downstream section through PDM to achieve information sharing and integration.
