摘要

The papermaking felt of high-speed papermaking machine vibrates seriously in a transverse direction. In this study, the transverse vibration of papermaking felt was analysed mechanically with respect to flexural rigidity, and a model was developed. The analytical resolution is obtained by the separation variable method. The result shows that it is a sinusoidal steady-state response. The natural frequency is calculated by the principle of free vibration. The flexural rigidity and density of papermaking felt are the main factors influencing its natural frequency. The validity of the model is verified theoretically and experimentally. The amplitude of the transverse vibration was tested by an optical non-contact measuring system. The amplitude-frequency characteristic curve shows that the natural frequency measured agrees well with the theoretical one.
