摘要：
With the development of urban transportation, vibration and noise control has attracted increasing attention. Vibration and noise level has become one of the important hallmarks of evaluating the influence of urban transportation to environment. As Tuned Mass Damper (TMD) is an effective means of vibration control, there is more and more emphasis on its research and application. Reasonably designed TMD can reduce vibration and noise caused by wheel/rail impact. So how to take into account the complex factors to improve the design of the TMD is still the important issue. TMD system is an effective structure. In order to study its vibration reduction effect, modal calculation and wheel-set drop simulation have been analyzed in this paper. Through varying the mass of TMD, the performance of vibration attenuation have been verified. The stability and performance of damping property under impact load have been confirmed by wheel-set drop simulation. Comparing the track which uses TMD and the normal one, the effect of TMD system can be testified effectively.
