从CAD系统到集成虚拟装配环境的数据转换研究

为了完成产品模型从计算机辅助设计系统到集成虚拟装配环境的数据转换，提出了信息提取模型转换法，将计算机辅助设计系统中的模型数据转换分解为信息提取和模型转换两部分，通过计算机辅助设计系统的二次开发和模型转换，得到集成虚拟装配环境所需的模型数据信息。以圆锥破碎机的进料机构为虚拟装配对象，在集成虚拟装配环境中对数据转换结果进行了验证，结果表明，用信息提取模型转换法获得的转换数据完整准确，转换效果良好。

Research on data transformation from CAD system to integrated virtual assembly environment

To transfer model data from Computer Aided Design(CAD) system to integrated virtual assembly environment, information extraction & model conversion method was put forward. In this method the process of assembly model transformation was divided into two processes, information extraction and model conversion.Model data information was transferred into the virtual environment by secondary development of CAD system and model conversion.Taking the feed device of taper crusher as a virtual assembly object, the result of data transformation in this integrated virtual assembly environment was verified. The application indicated that the method was feasible and the effectiveness of data transformation was validated.
