| 摘 要： | 动刀是玉米青贮切碎器的主要工作零件,同时也是受力情况最恶劣的零件。通过比较,选择合适的动刀片,并借助于Pro/MECHANICA应用材料力学及有限元方法对动刀片模型进行静态分析、灵敏度分析及优化设计,得到了满足优化约束的最佳参数和几何模型。优化结果表明,动刀片的宽度尺寸和螺栓孔的直径是影响动刀片性能的主要因素;同时发现,利用Pro/MECHANICA软件可以实现实体建模、结构分析及优化设计的无限集成,从而提高机械产品结构优化和新产品开发的效率。

| Abstract: | The blade is the most important working elements in the silage maize harvester, as well as the part that is subject to the worst force. To choose a appropriate blade and use Pro/MECHANICA to carry out static analysis, sensitivity analysis and optimization design of the blade by using material mechanics and Finite Element Method. As a result, it obtained the best parameters and geometry model which satisfied the optimization constraint. The optimization result showed that the parameters of the thickness of b... |
