EXPERIMENTAL RESEARCH ON THE DURABILITY OF VISCOELASTIC DAMPERS
-
摘要: 通过经老化的粘弹性阻尼器与未老化的粘弹性阻尼器的动态力学性能试验,阐明了粘弹性阻尼器中大部分粘弹性材料由于受到钢板的包裹,避免了直接接触空气,使其老化性能有很大提高。Abstract: It is introduced the experiment of the dynamic mechanical properties between the ageing viscoelastic dampers and the nonag ing viscoelastic dampers. It is also explained the improvement cause of ageing characteristics for VE dampers that the great majority of VE material is enwrapped by the steel plates to prevent from the air directly.
