【摘要】 为了支持机械产品自上而下、不断细化的设计过程，本文提出了一种以产品的装配结构为核心，由多个分析计算ａｇｅｎｔ组成的，支持异构分布环境的协同工作设计模式。产品的装配模型描述零部件的层次关系、位置关系等几何信息和装配语义信息、设计参数及其约束关系等工程语义信息，能够向各分析计算ａｇｅｎｔ提供必要的信息，以实现机械产品几何造型系统、装配建模系统、分析计算系统之间的有效集成。基于集成框架的分析计算ａｇｅｎｔ能够完成异构分布环境下协同设计过程中的逻辑推理、判断、分析计算等复杂工作更多还原

【Abstract】 In order to support the top to down decomposition process of mechanical products, this paper presents a cooperated design methodology which is based on the assembly structrue of the product and supported by a certain number of design agents. The assembly model of the product describes not only the geometric information such as hierarchical and position relationships of the parts and subassemblies, but also describes some engineering semantic information such as assembly semantics, design parameters and their constraints. It can provide enough information to the analyzing design agents. In this way, the integration among the geometry modeling system, the assembly modeling system and analyzing system is realized. The integration framework based analyzing design agents introduced here accomplish complicated logic deduction analyzing and calculating tasks in the cooperative design process under the heterogeneous environments.更多还原
