摘　　要：碰撞检测速度、网络延时和网络带宽对碰撞检测的限制是分布式虚拟装配系统中碰撞检测面临的主要问题。针对上述问题,提出了一种分布式碰撞检测解决方法,并对该方法中的同步方式、碰撞模型生成和几何元素间的相交检测进行了详细论述。应用结果表明该方法的有效性与实时性能够满足分布式虚拟装配的要求。The speed of collision detection, and the delay and bandwidth of network are the main problems in distributed virtual assembly environment. Based on the analysis of the problems above, a solution of distributed collision detection was proposed, and then the synchronization way, collision model production and intersect test way between geometry elements were discussed. The application shows that the algorithm works well in validity and real-time, and can effectively meet the requirements of the distributed virtual assembly.
