| 目的 建立椭圆齿轮-槽轮组合机构的虚拟样机， 并对其运动学与动力学特性进行仿真分析。方法 在 Matlab 中利用齿廓包络原理， 计算得到椭圆齿轮齿面数据， 将数据导入 SolidWorks 中建立椭圆齿轮三维模型， 并利用 Adams 软件建立椭圆齿轮-槽轮组合机构的虚拟样机， 最后将理论计算与仿真结果进行对比分析。 结果 仿真结果中的角速度与理论值基本一致， 角加速度在理论值上下波动，总体来看理论分析是合理的。 结论 改进槽轮机构角加速度最大值比原机构减小了 42.10%，最大应力降低了 38.52%，证明椭圆齿轮-槽轮组合机构应用于高速运转情况是可行的。 |

| Objective To establish a virtual prototype of elliptic gear-geneva combined mechanism, and analyze its kinematic and dynamic characteristics for stimulation. Methods Using the tooth profile envelope principle in Matlab, the surface data of the elliptical gear tooth was calculated. Then the three-dimensional model of elliptical gear was established using the data in SolidWorks, and the virtual prototype of the elliptic gear-geneva combined mechanism was built by the software Adams. Finally, the theoretical calculation and the simulation results were compared and analyzed. Results The simulation results of the angular velocity were in accordance with the theoretical value. Although the angular acceleration fluctuated up and down around the theoretical value, in general, the theoretical analysis was reasonable. Conclusion The maximum angular acceleration of the improved geneva mechanism was reduced by 42.10% compared to the original mechanism, and the maximum stress was decreased by 38.52%, which proved that the elliptical gear - geneva combined mechanism used in high speed condition was feasible. |
