中文摘要：
针对复杂产品装配设计过程中，零部件模型众多，数据量巨大，一般虚拟装配仿真软件无法进行实时处理的问题，提出了一种新型虚拟现实网格环境．该系统通过网格资源管理及共享技术聚合企业大量空闲计算资源，采用基于Sort—last算法和远程视频可视化的并行渲染框架支持实时交互式装配仿真．在汽车装配工位协同仿真中，该系统的主要设计功能和目标得到确认．仿真结果表明，在现有软硬件环境下，该系统能够较好解决大规模复杂场景的实时处理问题，同时可显著提高资源利用效率．
英文摘要：
Because of numerous component models and massive dataset in assembly design for complex product, common virtual assembly software can not process them in real-time mode. A new virtual reality grid environment was proposed, which uses grid resource management and shared technology to aggregate large numbers of idle resources in enterprise; uses parallel rendering framework based on Sort-last algorithm and remote video visualization to support real-time interactive assembling simulation. After taking a collaborative simulation for automotive assembling workstation, the main functions and design objectives of the system were affirmed. The result shows that the system can better solve the problem of real-time process for large complex scene in the present conditions of hardware, and observably improve the usage efficiency of enterprise resources.
