Dynamic Behavior of Brush Wheels for Scavenging Volcanic Ash.
1992
The dynamic behavior of rotational brush wheels, which are a main part of a road sweeper scavenging volcanic ash, has been examined experimentally. The vibration of polypropylene brush fibers has been recorded by a video camera and it has been analyzed to elucidate the dynamic behavior of brush fibers relative to the length and thickness of the fiber, the revolution frequency of brush wheel and the scavenging speed. Consequently, it is revealed that certain combinations of the natural frequency and wheel angular velocity should be avoided, and that scavenging speed hardly affects the dynamic behavior of the brush fiber.
