摘　　要：为了提高齿轮传动系统的设计效率,提出了一种支持齿轮传动系统分布式设计的协同设计环境。建立了齿轮传动系统的面向对象的模型,该模型能够表达齿轮传动系统概念设计阶段和详细设计阶段的产品信息,并支持概念设计阶段与详细设计阶段之间产品信息的传递。扩展了基于角色的访问控制模型,在标准模型中增加了属性元素,以满足协同设计环境中特殊的安全策略,能够保证共享信息的安全性,设计过程中,设计者根据其自身的角色,可并行地修改不同的元件。齿轮传动系统协同开发环境的构建以面向对象的产品表达模型和基于角色的访问控制模型为基础,实际工程应用说明了协同开发环境的实用性。A distributed collaborative design environment is presented to improve the efficiency of gear trains design. An objected oriented model for gear trains is built to support the expression of de- sign information both in conceptual design and detailed design and the exchange of design information between the two stages. To satisfy the security requirements of collaborative design environment, the role--based access control model is extended with attribute. The designers could concurrently modify different components of a gear train relevant to his or her role. The development of the design environ- ment is based on the object oriented model and extended role based access model, of which the engi- neering application approves its applicability.
