EB offset printing technology is a green printing method which solves the pollution in the packaging and printing industry from the root,and the central roller is one of the core components of the satellite EB offset printing machine,which is the main source of vibration of the whole machine,and its dynamic characteristics directly affect the quality of the printing and the production efficiency.Therefore,the dynamic characteristics of the central drum of the satellite EB offset press is studied.Firstly,the differential equation of the bearing-rotor system dynamics of the central imprinting drum is established;secondly,the influence of the different parameters on the vibration characteristics and stability of the rotor system is studied;finally,the influence of the circulating cooling water between the inner and outer walls of the drum is studied on the structure of the drum.The research results provide a basis for the fault diagnosis,structural optimization and stability analysis of the EB offset press center cylinder.
