在一个１：４的五层模型刚架结构上进行了变阻尼半主动结构控制振动台试验．在结构的底层安装了一个溢流阀式变阻尼控制器，输入几种不同的地震动并采用几种不同的控制算法对结构进行了变阻尼半主动控制。振动台试验结果表明，受阻尼半主动结构控制仅需要很少的电能，就可以达到较好的控制效果，是一种很有应用前景的结构振动控制方案。结合溢流阀式变阻尼控制器的特点，分析了一些因素对控制效果的影响．
A variable damping semi-active control shaker test was carried out on a 1: 4 five-story model frame structure. A relief valve variable damping controller was installed on the bottom of the structure. Several different ground motions were input and several different control algorithms were used to control the structure with variable damping and semi-active control. The results of shaking table test show that the damped semi-active structure control can achieve better control effect by using only a small amount of electric energy and is a promising vibration control scheme. Combined with the characteristics of relief valve variable damping controller, the influence of some factors on the control effect is analyzed.
