摘要
针对钢结构详图设计软件中构件连接之间相互碰撞以及螺栓安装预留安装空间问题,研究了如何快速有效地进行钢结构详图软件中三维模型碰撞检测,从而对构件、节点安装模型进行合理性检验。本文基于包围盒的思想,按照一定的规律提取三维空间物体几何数据,通过矢量法进行了物体之间空间相互位置关系判断,有效地解决了这一问题,编制了钢结构详图设计STXT软件碰撞检测及螺栓安放合理性检验模块。
In the detail structural steelwork,according to the problem of components in connection crashing at each other and the problem of the enough space of bolt installation,the paper expounds how to apply collision detection technology on steel structure designing software fast and effectively and then carries out reasonable test on component and node installation model. Based on bounding box and geometric data of objects in three-dimensional space obtained according to a certain rule,the paper deals with mutual relationship between spatial objects in the vector method and effectively solves the problem as well as finally programming collision detection model and bolt installation space test in the designing software of detail structural steelwork （STXT）.
