摘要

摘要: 复杂产品的实时碰撞检测是虚拟装配仿真过程中的计算瓶颈。在树形装配模型中，以面片表示的模型碰撞检测精度不足，而以实体建模的模型利用全局干涉检查的时间则开销太大，无法满足系统实时性要求。针对上述问题，提出了CAD环境中的分布式碰撞检测算法，CAD主机完成零件对的包围盒预碰撞检测，基于负载均衡原则，对需精确检测零件对进行任务分配并发送至CAD从机，而从机则完成零件对的精确碰撞检测及结果返回。仿真实验结果表明：该算法在满足精确性要求同时，能有效提高碰撞检测的实时性。

Abstract: Real-time collision detection is a bottleneck in a complicated assembly model, the collision detection precision based on face-representation can't satisfy the requirement in a level-assembly model, and the time consuming of solid model can't be accepted if using the global interference check. In order to solve the problem, a new distributed collision detection method was presented. Firstly, Master CAD finishes the collision detection of bounding box with AABB algorithm; based on the load-balance calculation principal, distributes component couples which need accurate collision detection and sends them to Slave CAD. Secondly, Slaves calculate component couples' collision detection and sent the interference results to Master CAD again. The results of simulation showed that the algorithm could improve highly real-time interference check in addition to meet the accuracy requirement.
