The Study of Physical Simulation and Numerical Simulation for Precision Forming of Spiral Bevel Driven Gear

通过对从动螺旋伞齿轮的精锻成形过程进行物理模拟和数值模拟研究,分析了成形过程中齿轮齿形的填充情况、等效应力等效应变的分布以及金属内部质点的流动规律,得出了从动螺旋伞齿轮精锻过程的金属流动规律,揭示了从动螺旋伞齿轮精锻过程的变形机理,物理模拟结果与数值模拟结果吻合。

Physical simulation and Numerical simulation for precision forming of spiral bevel driven gear are studied in this paper. Through the analysis of the filling condition of gear＇s teeth during the forming process, the distribution of equivalent strain and equivalent stress, and the flow law of inner metal particles, metal flow law are obtained in the precision forming of spiral bevel driven gear and deforming mechanism is il- lustrated. The numerical simulation results are in good agreement with the physical simulation results.
