The dynamic model of the servo system of the high speed and double side labeling machine for the whole automatic jelly food production was established. The equivalent moment of inertia and the equivalent stiffness of the servo system were obtained. The transfer function and the main vibration frequency of the servo system were obtained by means of the dynamic equation of the servo system. Through the root locus diagram and system vibration stability curve, the measures and methods were gotten to avoid or reduce the vibration principle to improve transmission system stiffness and cut work mechanism inertia and inertial components, loss of momentum or increasing damping, which can weaken the intensity of resonance. Using the correction network and integrated labeling film velocity feedback could also weaken the resonant.
