The transverse vibration problem for the paper web with the density linearly varying along its width was studied by use of the differential quadrature method. A transverse vibration model of printing paper web was established. The relationships of nondimensional vibration frequency versus nondimensional velocity, density coefficient and tension ratio of paper web were analyzed. The results show that the differential quadrature method is feasible in solving the transverse vibration problem of variable density rectangular moving paper web. The theoretical basis for improving the dynamic characteristics of paper web in printing was provided.
