在早期设计阶段，CAD（计算机辅助设计）工具之间的有效信息交换取决于所有 PLM（产品生命周期管理）工具中产品数据的标准化表示。 NIST 核心产品模型 (CPM) 及其扩展旨在提供所需的基础级产品模型，该模型是开放的、非专有的、通用的、可扩展的、独立于任何一种产品开发过程，并且能够捕获产品开发中常见的完整工程环境 [1,2]。开放装配模型 (OAM) 模型扩展了 CPM，为装配提供标准表示和交换协议。装配信息模型强调零件特征和装配关系的本质和信息需求。该模型包括作为概念的程序集和作为数据结构的程序集。对于后者，它使用 ISO 10303 的模型数据结构，非正式地称为产品模型数据交换标准 (STEP)[3]。本文的目的是展示如何使用 OAM 在产品设计的所有阶段实现产品信息的无缝集成，重点是装配。使用齿轮箱设计示例来说明该过程。
In early design phases an effective information exchange among CAD (Computer Aided Design) tools depends on a standardized representation for the product data in all PLM (Product Lifecycle Management) tools. The NIST Core Product Model (CPM) and its extension are proposed to provide the required base-level product model that is open, non-proprietary, generic, extensible, independent of any one product development process and capable of capturing the full engineering context commonly shared in product development [1,2]. The Open Assembly Model (OAM) Model extends CPM to provide a standard representation and exchange protocol for assembly. The assembly information model emphasizes the nature and information requirements for part features and assembly relationships. The model includes both assembly as a concept and assembly as a data structure. For the latter it uses the model data structures of ISO 10303, informally known as the Standard for the Exchange of Product model data (STEP)[3]. The objective of the paper is to show how the OAM can be used to realize seamless integration of product information, with an emphasis on assembly, throughout all phases of a product design. A gearbox design example is used to illustrate the process.
