摘要
利用形状记忆合金超弹性变形下的滞回耗能性能,设计了一种 SMA-橡胶复合隔震支座,建立了隔震支座的力学模型,对其隔震性能进行了研究。结果表明,本文提出的 SMA-橡胶复合支座良好地改善了橡胶支座的隔震性能。
By utilizing hysteretic damping capacity resulting from superelastic deformation of shape memory alloy,a new type of SMA-rubber composite bearing is designed.A mechanical model is established and the seismic isolation performance of the bearing is investigated.It is shown that the proposed SMA-rubber composite bearing provides more excellent seismic isolation performance than ordinary rubber bearings.
