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.
