The precondition of improve the printing press velocity is to maintain the minimum vibration of infeed unit within the range of press speed. Taking advantage of the equivalent relation between the formula of infinitesimal energy and the classic beam theory, the vibration of convey paper belt can be converted into the problem of the beam be stretched and be compressed, and then we utilize the finite element simulation technology to conduct model analysis for the convey paper belt. When the numerical of the belt speed gain ,both the vibration and shape distortion reach the maximum, as well as speed of the infeed unit will be influenced most.
