 摘要： 将伪弹性形状记忆合金拉索用于高耸化工塔振动控制，在考虑形状记忆合金材料非线性及形状记忆合金与化工塔变形相互耦合的基础上，联合采用有限元法和纽马克积分法研究该化工塔的风振响应特性。通过与未装拉索和装入普通拉索的高耸化工塔相比较，发现伪弹性形状记忆合金拉索对高耸化工塔有较好的振动抑制效果。

Abstract: The pseudoelastic shape memory alloy (SMA) cables were used for vibration control of a highrise chemical tower in the present work. On the basis of taking into account the material nonlinearity of SMA and the coupled action of deformation between SMA and the chemical tower, the dynamic response of windinduced vibration of the chemical tower was studied by combining the finite element method and the Newmark integration method. The results were compared with those of the chemical tower without any cables and under the control of common cables. It is found that pseudoelastic SMA cables have good vibration suppression effects on the highrise chemical tower.

Key words: shape memory alloy; high rise chemical tower; vibration control; wind induced vibration response
