Sound and vibration of railroad wheel
Proceedings of the 1996 ASME/IEEE Joint Railroad Conference, 2002Vibrations generated at the contact surfaces between rails and wheels have been considered to be the main cause of noise from railroad vehicles. These noises are classified into three types: rolling, impact, and screech noise. The generation mechanism of each noise has not yet been clarified.

Ring model of railroad wheel vibrations
The Journal of the Acoustical Society of America, 1983This paper presents a model for prediction of the vibration characteristics of railroad wheels. Earlier workers showed that the ring theory gave a good explanation of the ratio of resonant frequencies in the railroad wheel, assuming flexural modes are excited in the rim.

Noise and Vibration from Railroad Traffic
2012The overdue beginning of new construction and development of train tracks since the 1960s coincided in the 1970s with an increasing sensitivity of the population towards noise, especially road traffic noise. This sensitivity has constantly increased since then and has significantly influenced the legislation concerning traffic noise.

Optimization of railroad vehicle vibration damping
Strength of Materials, 19701. The first condition of optimization of a shockproof system by damping should be optimization according to the rigidity parameter, decreasing the energy transfer of coordinate vibrations under critical conditions or excluding the summation of their maxima. 2.

Response of Railroad Ballast to Vertical Vibration
Transportation Engineering Journal of ASCE, 1978The effect of vertical vibration on some railroad ballasts in laboratory tests is presented. The ballasts were found to behave in a similar manner to that previously reported for sands, i.e., peak acceleration was the main parameter affecting densification. For unsurcharged ballast, little increase in density occurred at peak accelerations below 1 g, a

Utilization of Waste Tires to Reduce Railroad Vibration
Materials Science Forum, 2007This study proposes a means to recycle waste tires as a material to reduce ground vibration. A series of field experiments was carried out to assess the reduction effect of railroad transport vibration by utilizing waste tire chips. The ground vibration during the railroad transport operation was measured in two railroad lines to investigate the ...
