Pin-pin resonance as a reference in determining ballasted railway track vibration behaviour

Pin-pin resonance is one of the most significant preferred vibration modes of beams, which are supported at equal distances, such as rails at sleepers in railway track structures do. Pin-pin resonance is a vibration that appears in one basic (first) mode and several higher modes, however the basic mode will have the highest amplitudes. In...
