摘　　要：以共轭齿面包络原理为理论基础,布尔运算为方法,商用三维软件为工具,进行了齿轮加工制造的计算机模拟与仿真研究。取磨前滚刀加工圆柱齿轮为对象,给出了刀具与齿轮之间相对运动关系v12的计算机实现过程,和在商用软件平台上实现齿面包络生成原理的方法与步骤。文中提出的方法无需推导齿轮实体的曲面方程就能够准确、真实地模拟制造过程,建立实际的齿轮齿面几何模型,为复杂曲面零件的CAD/CAE建模与分析提供了新途径。Based on the gear generation principle, taking the Boolean calculation as the method and using commercial three dimensional software as the tool, the research on modeling gear manufacture processing is carried out. By taking the manufacture of spur-gear using pre-grinding hob as example, using Pro/Engineer to set up accurate three-dimension solid model of cylindrical gear, a new way of getting FEM geometry model of complicated curve surface parts is put up. Because the developed method can model all kinds of cylindrical gear with not having to deduce the equation of involute and transition curve, it lays the foundation for the CAD/CAM modeling, especially for modeling of the parts of complicated curved surface.
