摘　　要：通过分析复杂产品协同设计的特点和高层体系结构(high level architecture,简称HLA)在工程设计领域中的应用,构建了一种基于HLA的联邦式协同设计系统体系结构,阐述了系统中各平台的组成和功能.为确保协同设计过程中联邦成员收发数据的一致性,提出了各平台中联邦成员的时间管理策略,给出了系统整体时间推进的方法和过程.在时间管理策略的基础上,通过采用设置内部和外部事件逻辑计数器方法和基于仲裁的锁定机制,实现了系统运行过程中设计邦员动态注册的初始一致性.A federal system architecture based on HLA for collaborative design was constructed and the structure and function of the platforms were explained by analyzing characteristics of collaborative design for complex products and applications of High Level Architecture(HLA) in engineering collaborative design.To deal with the problem of data consistency in the process of designing,time management strategies of federates in every platforms were proposed,and the procedures of system time advancing were given.Meanw...
