摘要：A numerical method is proposed to calculate dynamic dissipated energy for mixed structures including elastic materials, viscoelastic materials and porous materials. An expression to calculate share of dissipated energy for an each element in the mixed structures is derived. Using this expression, vibration transmission properties are analyzed for mixed structures composed of a porous material sandwiched between a steel beam with a damping material and a resin sheet. Further, a spacer is installed between the steel beam and the resin sheet in the structures, to analyze deterioration of vibration by the sound bridge phenomena.
