Modelling and Performance Analysis of Rail Vibration Absorber by FE and BE Methods

  • Conference paper
Book cover Noise and Vibration Mitigation for Rail Transportation Systems

Part of the book series: Notes on Numerical Fluid Mechanics and Multidisciplinary Design ((NNFM,volume 118))

Summary

A finite element model of the railway track with a rail absorber is proposed for investigating the effects of the absorber’s multiple motions on the dynamic behavior of the track. The rail vibration and radiation due to a roughness excitation are calculated with the use of the absorber. The calculation results are compared with those of the beam-spring model. The results show that the radiation efficiency of the rail with the absorber is significantly reduced in the frequency range 300-1000 Hz. The noise reduction calculated by the finite element model is less than that of the beam-spring model in the frequency region of 400-—1000 Hz due to the transversal rotation of the absorber. The rail-radiated noise can be reduced by about 7.1 dB(A) using the rail absorber.
