摘要
虚拟装配系统可对机电产品进行装配仿真,生成装配顺序与装配轨迹,而碰撞检测技术正是对装配顺序与装配轨迹的正确性进行验证。把虚拟装配环境的碰撞检测算法归类为:基于时间域的碰撞检测算法、基于几何空间的碰撞检测算法、基于图像空间的碰撞检测算法。对这几类算法的研究现状进行了综述,根据研究现状分析了碰撞检测算法中存在的问题及研究难点,并对碰撞检测算法的研究趋势进行了展望。
The virtual assembly system can simulate the electromechanical products to generate the assembly sequence and assembly track,and the collision detection technology is used to verify the correctness of assembly sequence and assembly track.The collision detection algorithms in virtual assembly environment mainly include algorithm based on the time,algorithm based on geometric space and algorithm based on image space.A survey on the present situation of these algorithms was proposed.At last,the current problems,future research direction and difficulties of collision detection algorithm were discussed and analyzed based on the survey.
