Abstract:The related problems in tube bending process of reactor in-core (RIC) measurement guide tube are presented, and algorithms of conversion from tubular coordinate to machining coordinate and collision detection are constructed according to tube bending principle of CNC tube bender. Based on OpenGL graphic library, parametric modeling for NC tube benders and RIC measurement guide tubes is established, and tube bending process is simulated. By using of bounding box detecion technology, simulation analysis of collision between RIC measurement guide tubes and tube bender bed body or kinds of tube bending mould is fullfilled, so as to confirm the bendability of a tube. With the technology, the tube design and tube bending technology are combined organically, and the tubes can be bended successfully without trial-bending.
Key words:RIC measurement guide tube;collision detection;bendability
