| 摘 要： | 将形状记忆合金(SMA)索与普通叠层橡胶垫复合可以形成具有滞回阻尼性能的SMA-橡胶隔震支座。在原SMA-橡胶支座(I型)的基础上,在支座中增加弹簧改善SMA耗能拉索的功能,设计了II型SMA-橡胶支座,建立了支座的理论模型。通过数值计算详细考察了此种支座的工作特性,并与Ⅰ型SMA-橡胶支座的性能进行了对比。

| Abstract: | The SMA-rubber bearing with hysteretic damping is initially developed by incorporating SMA wires and laminated rubber pad.Based on the existing SMA-rubber bearing(type I),type II SMA-rubber bearing is designed by adding spring elements which are used to improve the functions of SMA wires.A theoretical model of type II SMA-rubber bearing is established.By numerical simulation,the working behavior of type II SMA-rubber bearing is discussed in detail and is compared to that be exhibited by type I SMA-rubber bearing. |
