摘要
针对虚拟预拼装时钢结构构件在拼装后可能存在的碰撞问题,基于包围盒算法和空间三角形相交检测算法,编制了碰撞检测程序,有效地解决了这一问题。并通过两个实例验证虚拟拼装环境下碰撞检测程序的可行性与效果。结果表明:按所提方法,虚拟拼装环境下碰撞检测具有较好的可行性,适用于实际工程。
In order to solve the problem of possible collision of steel structural after virtual assembly,the paper developed a collision detection program based on the bounding box algorithm and the spatial triangle intersection detection algorithm,which effectively solved this problem.And the feasibility and effectiveness of the collision detection program in the virtual assembly were verified by two examples.The results showed that:according to the proposed method,the collision detection in the virtual assembly had good feasibility and is suitable to practical projects.
