一种适用于较宽环境温度的粘弹性阻尼器

Viscoelastic Dampers Adaptable to Wide-Environment Temperature

环境温度是影响粘弹性材料耗能性能的一个重要因素 ,每种粘弹性材料都有其最佳适用温度区间 ,超出此区间后其耗能能力非常有限 ,这一点限制了粘弹性阻尼器在更广的范围内应用 .把适用于不同温度区间的两种粘弹性材料复合使用 ,使粘弹性阻尼器在较宽的温度区间内具有良好的耗能性能 ,拓宽了粘弹性阻尼器的应用范围 .

Environment temperature is an important factor that affects energy dissipation capability of viscoelastic(VE ) material. Each type of VE material has its optimal range of applying temperature. The energy dissipation capability would be limited if the environment temperature overstep the range. This limited the application of the VE dampers to more structural types. The compound use of two different type of VE material, which has different range of applying temperature, makes VE dampers have good energy dissipation capability in a large range of temperature and enlarges the applying range of VE dampers.
