Title:
REDUCTION SYSTEM OF STEEL SHEET VIBRATION-RESONANCE SOUND
Document Type and Number:
Japanese Patent JP2014043927
Kind Code:
A
Abstract:

To provide a reduction system for reducing the vibration of a steel sheet and the vibration-resonance sound.

A system reduces the resonance sound which is generated by the vibration of a steel sheet 2 or a component of a hopper 1 to be used at a dam-building site, for example. A shaker 4 is disposed for vibrating the steel sheet 2 or an object of vibration reduction. When the steel sheet 2 or the vibration elimination object vibrates, the vibration and the accompanying resonance sound of the steel sheet 2 are reduced and attenuated by applying vibrations of an inverse phase for eliminating the vibrations by the shaker 4.
