摘要

本文设计了一种拉压型形状记忆合金（SMA）阻尼器，对广东省的一座古塔进行减震控制。通过把SMA阻尼器安装在古塔上，可同时减少古塔在水平地震和竖直地震作用下的响应。采用大型通用软件ANSYS对古塔安装和不安装SMA阻尼器结构分别进行了有限元仿真分析，对结构的动力特性、水平地震反应和竖向地震反应进行了分析和对比，探讨了SMA阻尼器的控制效果，分析结果与振动台试验数据进行了比较，验证了分析结果的可靠性。

Abstract

A type of SMA tension and compress damper has been designed to control vibration of an ancient pagoda in Guangdong in this paper. Through installing the SMA damper in the ancient tower, the seismic response of horizontal earthquake and vertical earthquake has been reduced. Through the utilization of ANSYS, the simulation analyses between the ancient pagoda which installed SMA damper or not install SMA damper are made respectively on horizontal earthquake and vertical earthquake to examine the control effect of the SMA damper. Analysis Results are compared with the shaking table experiment results. The energy dissipation capacity of the SMA damper designed by this paper has been verified.
