Abstract


The tuned mass damper was applied to vibration control of transmission tower. The paper set up the finite element model of the tower using the beam element. Then, the simplified multi-particle model was presented. For vibration control of the first mode, an equivalent single degree of freedom model was further established. The paper designed a kind of suspended tuned mass damper using the simplified model. The transmission tower rig was built for vibration control test. The frequency response function of the system before and after the installation of the damping device was compared using the impacting test. Test results show that the suspended tuned mass damper has a vibration control ratio of 50.8%. The effect of vibration control is obvious.
