Study of field testing on car body vibrations of moving passenger car with wheel flat

Abstract

The article analyses the methodology of experimental investigations of railway vehicles under real operating conditions. The aim of the research is to determine the vertical and lateral accelerations of the carbody of passenger car with a wheel flat by running along the same track at different speeds. Statistical analysis of the obtained data was performed. Experimental results were evaluated using shock acceleration ratio and Sperling ride index was calculated. General conclusions are given.
