Study on Measurement Repeatedness of Vertical Impacts on Rail of Loaded and Empty Wagons
Santrauka
The paper investigates the question of the repeatedness of the results of the measurement of the impact of a wagon wheel on the rail. It is examined how the dispersion of the impact values depends on whether the wagon is loaded or empty. The ratio of the total width of the two middle quartiles to the median is used as a parameter to assess the predictability of the effect of wagon wheel damage on vertical impacts. The results of field tests were used for the research, and conclusions were presented.
