Abstract: A parameterized computer aided design method and key technology of the combine threshing cylinder based on 3D solid modeling are introduced. The structure models and the analyzed solving algorithms of parameterized design of the threshing cylinder are presented, the threshing cylinder CAD system is studied in secondary developing environment of MDT. A practical design case shows that it benefits serialized production and improving the efficiency of design.
Key words: CAD  Combine harvester  Threshing cylinder  Parameterized modeling
