Influence of inaccuracies and measurement errors on frequency of uncoupling of cars for unscheduled repairs on the railways of the Republic of Uzbekistan

Abstract

Objective: Considering the impact of inaccuracy and errors in measuring the thickness of the fl ange of wheelsets on the frequency of uncoupling for unscheduled repairs on the railways of the Republic of Uzbekistan. Conducting an analysis of the impact of uncoupling freight cars for unscheduled wheelset malfunctions repairs. Methods: Methods of combinatorial and statistical analyzes of the initial data are used. Results: A detailed analysis of car uncoupling for unscheduled repairs on the railways of Uzbekistan has been carried out. The probabilities of car uncoupling operation in TR-2 (current repair) due to the “thin fl angeˮ malfunction have been determined. The infl uence of inaccuracies and measurement errors on the frequency of uncoupling of cars for such a repair is estimated. Practical importance: The results obtained contribute to the deepening of knowledge about the possibility of the infl uence of inaccuracies and errors in measuring the thickness of the fl ange of wheelsets on the performance of cars.
