Abstract: Installation of rail vibration dampers (rail dampers for short) onto rails between sleepers is one of the measures to control rail noise generation and roughness growth. Amid the rapid expansion of high-speed and underground railway networks in China, many suppliers are actively marketing and promoting their products, often giving confusing information. In this paper, a parametric study is used to investigate the effect of rail dampers on the dynamical behavior of a Chinese high-speed railway track. The Fourier transform-based method developed for analyzing dynamics of a railway track as an infinitely long periodic structure, with or without rail dampers, is applied in the investigation. It is hoped that results in this paper can help develop the understanding of the working mechanism of rail dampers, and provide useful information for product design and application.
This paper investigates the effect of rail dampers on the dynamical behavior of high speed railway track. The Fourier transform-based method is applied to solve the motion equations. The dispersion curves of track, vibration decay rates and vibration energy of both original track model and of the track model with rail dampers were studied. This research does help readers to understand more about rail damper with the parametric study. And in the meantime, the dynamic proper of track under a moving load was analyzed. This research is quite meaningful.
