| Research Abstract |
In this study, the properties of viscoelastic damper during long duration random vibration are discussed. Analytical and experimental results show that temperature inside the viscoelastic material body become stable by effect of heat conduction & heat transfer even if the damper is vibrating randomly. In addition, the simplified evaluation method using sinusoidal-wave to substitute random time history data are propertied.
