Abstract: A torque synthesizer was used in an electric load simulator to analyze its synthesis efficiency under different input conditions. A 3D model was established with Solidworks and transferred from Parasolid into ADAMS. Then, the contact force between gears was calculated and constraints were imposed to set up a dynamic model for torque synthesizer based on the Hertz elastic collision theory. The torque of different sizes, orientation, frequency, phases and forms were input to get the dynamic response curve of output torque. Simulation results show that the deviation between simulation value and theoretical value is within 1%, which has proved that the torque synthesizer is efficient in all input conditions and the model established is reliable and accurate. The study results are conducive for the use and further structural optimization of torque synthesizers.
