Abstract
The characteristics of vibration damping steel sheet, which has three layered structure of steel/viscoelastic resin/steel, were examined. They were affected theoretically by material conditions, such as viscoelastic properties of resin and configuration of each layer, and also by mechanical vibration conditions, such as vibration mode and supporting condition. The influences of material conditions on the loss factors were examined experimentally under several constant conditions of mechanical vibration conditions. It is concluded from the present results that loss factors of vibration damping steel sheet are determined by not only a loss factor of resin itself but also rigidity and thickness of resin as well as steel sheet. These results give a guide for the best suitability for a loss factor of vibration damping steel sheet.
