| Abstract: | Kinematical modeling for main machines is one important objective for virtual manufacturing systems, e.g. beverage packaging production line. It is important to improve the kinematical modeling efficiency in virtual environment for promoting realtime simulation . Case-unloader two concepts, peer model and auxiliary node, are firstly put forward in this paper to lever kinematical modeling for case-unloader in virtual environment. The advantages are that they combine with the motion characteristics of the machine, take fully advantage of the scene elements and tree hierarchy structure of World ToolKit, improve modeling efficiency, are easy to understand and implement. Kinematical modeling for the machine is described in detail and motion graph is given in this paper. |
