摘　　要：为了研究调谐质量阻尼器(tuned mass damper,TMD)在海洋平台冰激振动中的减振效果,提出一种基于半仿真实验系统的TMD等效阻尼力测量方法,利用该系统可以直接测试结构安装TMD装置时产生的作用力。介绍该实验系统的测试原理及等效阻尼力的测量方法,并在正弦位移输入下,对TMD装置进行了测试,比较等效阻尼力的实测值与计算值,结果证明利用该系统可以测量得到TMD的等效阻尼力。In order to assess the reduction effectiveness of TMD to mitigate ice-induced vibrations of platforms, the method of measurement of equivalent damping force of TMD based on semi-simulation experimental testing system is presented. The interaction force between TMD and structure can be measured directly by this system. In this paper, the principle and the method of force measurement are introduced. The force comparison between experimental value and calculated one is made under sinuseidal displacement input. Experimental results show that the force measured from load cell is almost equal to the inertial force of TMD. Therefore, the feasibility of using this system to measure equivalent damping force of TMD is confirmed.
