Taking the new hybrid multi-stage serial planetary gear reducer as research object

the dynamics model is constructed using the joint modeling methods

defined movement relationship and applied load for the model using Step function

dynamic simulation is carried out.The relative motion among the various components can be real-timely and dynamically observed

and the instantaneous motion results of each components can be real-timely measured.By FFT transform to the key components

the curves in time domain and frequency domain about meshing force are obtained.Compared with the theoretical analysis results

the simulation results and theoretical analysis results are consistent.
