Abstract
This paper presents an experimental study on damping characteristics of a square pipe packed with steel balls and silicon oil. The effects of steel ball diameter, total mass of steel balls, and viscosity of silicon oil on the vibration damping characteristic and sound characteristic are examined using impulse excitation method. It is shown that the damping characteristics are strongly affected by the diameter of steel ball and the viscosity of silicon oil, and that the sound characteristic is significantly improved by packing the pipe with steel balls and silicon oil. It is also shown that the damping capacity becomes the maximum at a certain value of the parameter, μ/d2ρP, where μ is the liquid viscosity, d is the ball diameter, and ρP is the ball density.
