摘　　要：创新性地设计了一个基于特征实体造型的CAD-Grid分布式系统(CGDS)的框架。展现了一个新的基于网格技术的分布式协同CAD系统环境,该系统平台以通用网络为基础,以各种CAD设计资源为结点,以网格平台中间件GlobusToolkit3.0为桥梁,整合了由网络服务实现的任务动态调度、分布式执行的机制,实现资源共享、协同设计,加快了CAD实体建模。通过实例验证了系统的可行性和可操作性。实验证明,并非节点数越多越好,只有当节点数与零件图个数遵循Amdahls法则时,其加数比和效率达到最佳值。The paper presents a novel CAD-Grid distributed system （CGDS） for feature-based solid modeling. A prototype system, named CAD-Grid, is integrated with WEB services-based distributed-computing technology. The paper describes the Grid computing environment of CAD-grid, its structures, the system simulation to which CAD-Grid was applied, and also the application results. The feasibility and practicality of the system are verified by examples. At the same time, after studying the functions and the characteristics of the system management nodes, the paper points out that configuration nodes is very important in choosing resources nodes.
