Nowadays, the increase in heavy freight rail transport and high-speed train (HST) operations has encouraged scientists to investigate dynamic response of structures under moving load using analytically numerically computational methods. In this study, analyse vibration structure, been modelled as continuous Euler-Bernoulli elastic beam system. The effects some basic parameters such track founda...

An annoying tonal noise is produced by modern electrical trains during acceleration and deceleration. This noise is caused by electromagnetic forces generating structural vibrations, especially from the traction motors. The electromagnetic noise is dominant at low train speeds and affects both the passengers on the train and on platforms, as well as people living near the track. The focus on th...

Background: Noise-induced hearing loss is a sensorineural hearing loss, which is associated with exposure to high levels of sound. Since train drivers exposed to high noise levels and the use of hearing protection devices is relatively difficult and they also need to hear the radio communications, this study examines the hearing status of train drivers of Yazd Railway Company. Methods: This i...

Exploding wires are widely used in many experimental setups and pulsed power systems. However, many aspects of the process of wire fragmentation still remain unclear. If the current density is not too high, the wire may break up in the solid state. The experiments have shown that the wires break in tension due to longitudinal forces of unknown nature. In a series of papers, see [2, 3, 4, 5] Gra...
