Experiment on Vibration Reducing Capacities of Pore Viscous Damping and Liquid Film Damping
Recently, we develop a new method for reducing vibration named liquid film damping (LFD) which combines the mechanism of vibrational energy dissipation of liquid viscous damping (LVD) and air film damping (AFD). This paper use experiment to compare the capacities of vibration decreasing of LFD and the pore viscous damping (PVD) which is an extensive applied type of LVD. The results of experiment present LFD has better ability than traditional LVD in reducing vibration of structures in not only higher frequency but lower frequency.
