Abstract: The damping of paper vibrating in air is studied by means of vibration experiment. Based on the experiment, a new method and steps are presented to construct the damping matrix in the finite element method a nalysis of paper's dynamic response. With the constructed damping matrix, the dynamic response of cantilever paper due to gravity loading is analyzed. The calculated result is compared with test data and the agreement is very good. It is proved that the damping matrix constructed can truly describe the paper's damping property.
