The calculation of transmission ratio of epicyclic gear train is the key and difficult content in basic mechanics teaching.Its calculation principle is more abstract and the process is more complicated,which it is not easy for students to master.In order to solve it more simply and efficiently,this paper first establishes the model of each part of the epicyclic gear train by using Solidworks,and completes the simulation model assembly.Secondly,the motion process of the epicyclic gear train is simulated with Solidworks motion analysis module.Finally,based on the simulation results,the transmission ratio of the epicyclic gear train with complex structure is calculated.The results show that it is close to the theoretical calculation results,which proves the feasibility of using this method to calculate it.
