Vibration and noise measurement synchronous and analysis on paper transmitting system for sheet-fed offset press

The method of synchronously measuring vibration and noise is brought forward on paper transmitting system to solve the problem of excessive vibration and noise on paper transmitting system for sheet-fed offset press and then to improve its precision. Paper transmmitting precision is influennced by excessive vibration of paper transmmitting system for sheet-fed offset press, leading to printing trouble of overlap error at a high speed. And noise level of gripper opening and closing teeth is one of the important performance indicators for sheet-fed offset press. Aiming at excessive vibration and noise of paper transmitting system for sheet-fed offset press, the principle and composition was presented in this paper. Moreover measurement at worksite was carried out. By experiment and analysis, it´s known that noise level of gripper opening and closing teeth seriously affects sheet-fed offset press. The conclusion acs as the foundation for trouble diagnosis and renewing design of sheet-fed offset press.
