    • Abstract
  • The short and long rail test models were designed. Through the test of hammer, the vibration level and the vibration attenuation rate of the rail were compared and tested before and after the damper installation. The results show that the tuned rail dynamic absorbers can effectively reduce the vibration level of the structure near the design tuning frequency(100~600 Hz), the main vertical and transverse max responses can be reduced by more than 3 dB. In addition, the vibration absorber can effectively block the transmission of vibration energy along the rail surface. Within the full frequency range of 0.1~1 kHz, the rail attenuation rate increases by varying degrees.
