The key part of pushing mechanism was analyzed, which included pendulum, power shaft, and grooved cam, to solve the vibration problem caused by high-speed pushing mechanism of book packer. The solid models of the pushing mechanism were built using SolidWorks software. The models were than transmitted into ANSYS and ADAMS software, in which the finite element analysis and dynamics analysis were completed. The simulation result showed that the vibration performance and dynamic characteristics of pendulum, power shaft, and grooved cam can meet the requirements of practical engineering application.
