Measurement and analyses of vibration into gravel ballast of rail and tram tracks

The article is aimed at the measurement and the analysis of vibrations of gravel ballast of rail- and tram tracks. The vibration of railway tracks with gravel ballast is influenced by the quality of ballast, traffic load and structural conditions (homogeneous or mixed traffic, speed, roughness of runway or vehicles etc.), climate factors (temperature, humidity, dryness, frosts etc.) and especially by dynamic loading from wheelsets of rail vehicles. Some dynamic characteristics of the rail or tram track can be measured and analysed easily indirectly with the help of acceleration sensors (eventually sensors of speed or vibration amplitude) placed on different points of the rail, respectively on sleepers or rail holds. For the study of vibration phenomena, which take place in rail, it is necessary to use sensors built into the ballast layer so that the conduction of vibration toward sensors is sufficient and there is no damage of sensors. The article contains the theoretical study of the task, the methodology used and the real experiment of vibration measurement into gravel ballast. The results include recommendations for practical experiments in traffic. For the covering abstract see ITRD E125214.
