A suspended monorail transit system is a category of urban rail transit, which is effective in alleviating traffic pressure and injury prevention. Meanwhile, with the advantages of low cost and short construction time, suspended monorail transit systems show vast potential for future development. However, the suspended monorail has not been systematically studied in China, and there is a lack o...

Rail corrugation is a common railway defect that involves diverse and complex factors. grinding also the most commonly used method to address corrugations. Through numerous irregularity tests one-third octave frequency spectrum analyses, this study determined characteristics development process for rail on high-speed tracks. The vibration transmission properties of train were tested using force...

The environmental effects of ground-borne vibrations generated due to localised railway defects is a growing concern in urban areas. Frequency domain modelling approaches are well suited for predicting vibration levels on standard railway lines due to track periodicity. However, when considering individual, non-periodic, localised defects (e.g. a rail joint), frequency domain modelling becomes ...

The dynamic performance of straddle monorail train is closely related to the track irregularity. However, there little research on irregularity , and its semi-random particularity makes it impossible use existing spectrum. In this paper, running surface PC beam measured, elevation map drawn, expression random obtained; finger-band deflection under dead load are studied; a method proposed descri...

The purpose of the following paper is to present author’s experimental field investigations a jointless railway track subjected generated imperfection and analysis response applied static loads. An optical measurement system, Pontos, was used for dynamic track’s deflections in 3D. allow us recommend direct application this system non-contact measurement, visualization simulated defects track, a...
