| 摘 要： | 粘弹性阻尼器是有效的被动消能装置,普通粘弹性阻尼器的力学性能主要受环境温度、激励频率和应变幅值的影响,对结构的设计结果会产生偏差.新型粘弹性阻尼材料,其力学性能不受环境温度和激励频率的影响,通过与普通粘弹性阻尼器动态力学性能的对比,可见新型粘弹性阻尼器作为耗能元件,对消能减震结构的设计结果会比较精确.

| Abstract: | The viscoelastic damper is a kind of effective passive energy-dissipating device. The mechanical property of ordinary viscoelastic damper is affected by environmental temperature, incentive frequency and strain amplitude and may produce deviation to the results of structural design. This paper introduce a new viscoelastic damping material, whose mechanical property are unaffected by environmental temperature and incentive frequency. The dynamic mechanical property of new viscoelastic dampers adopting the new visco- elastic damping material and that of ordinary viscoelastic damper are contrasted. Our study shows that the results of the energy-dissipating and shock-absorbing structure adopting the new viscoelastic damper as en- ergy components is more accurate and efficient. |
