摘要:
针对CREO三维线缆具有柔性可随意变形特性而引起难以进行干涉检测的问题,提出基于离散点距离的三维线缆干涉检测算法。该算法通过线缆中心线动态离散点对三维线缆进行表达,分析结构件的空间位置关系,利用线缆与线缆、线缆与结构件之间的空间位置关系进行干涉检测,实现了对三维线缆进行快速干涉检测的目的。最后在Visual Studio 2010与CREO 平台上采用C++语言和TOOLKIT工具对所提算法进行了验证。结果表明该算法具有较好的快速性与准确性,可以满足工程实际需求。
To solve the problem that the virtual 3D cable of CREO can easily cause interference detection difficult because the cable has a flexible optional deformation characteristic, an algorithm that expresses the cable discretely by using dimensional coordinates point is put forward. Firstly, the algorithm expresses the cable entities by using cable centerline discrete spatial coordinates point. Secondly, space position relation of structure is analyzed. Finally, by utilizing the relationship of space position between cables as well as cable and structure, the fast interference detection for 3D cables is realized. The algorithm is validated on the platform Visual Studio 2010 and CREO by using C++ language and TOOLKIT tools. The results show that the algorithm is fast and has better accuracy to meet the actual needs of the project.
