Research on pipe design technology under complex assembly environment
复杂装配环境约束下管道设计研究

This paper analyzed the pipe design difficulties in the complex assembly ,proposed a new pipe design method based on noninterference detection which reducedthe difficulties of computation by converting interference analysis from 3D to 2D. Simplified the complex assembly access identification is simplified to the polygonal largest inscribed circle computation. Determined the pipe route by the spline interpolation whose nodes were the centers of polygonal largest inscribed circle list. Optimized the pipe route by the lines approach to curves. Using the method, implemented the pipe instant-formation under complex assembly without interference check.
