摘　　要：针对部件级别的协同虚拟装配,提出了协同虚拟装配环境下的模型表达方法和数据转换方法。该方法根据协同虚拟环境下交互装配仿真需求,将部件模型分为显示层、逻辑层、碰撞检测层、部件信息层,形成具有四层次的产品模型表达。开发了数据转换接口,获得了四层次的产品模型。在汽车部件级别虚拟装配的应用表明,该模型表达和数据转换方法能够满足协同虚拟装配交互仿真需求。Aiming at product information modeling in the collaborative virtual assembly systems, a four-level model representation and the data transformation methods were put forward. To deal with simulation requirements of interactive assembly in collaborative assembly environment, the component model was categorized as： display layer, logic layer, collision testing layer, and components information layer. A data transformation interface was developed to get the four-level product model. Application in automobile collaborative assembly showed that the model representation and the data transformation interface could meet the product information need of the collaborative virtual assembly.
