Information × Registration Number 0123U101519, ( 0226U001309  ) R & D request Title Experimental and theoretical studies of the dynamic performance of the rolling stock of railways in interaction with the lower and upper structures of the track Head Kovalchuk Vitalii V., Доктор технічних наук Registration Date 08-03-2023 Organization Lviv Polytechnic National University popup.description1 To conduct a series of experiments in the accelerated movement of a railway train, on the basis of which to determine the dynamic performance and traffic safety indicators. In parallel, a mathematical model of the rolling stock is being created, the adequacy of which will be verified by comparing the calculated data with the results of the experiments performed. With the help of the developed model, the forecasting of the behavior of the existing railway rolling stock during high-speed traffic will be carried out and conclusions will be drawn about the features of the operation and maintenance of the constituent elements of the rolling stock, as well as the lower and upper structure of the track at speeds from 200 to 250 km/h. So, the object of the study is the rolling stock, which is used to organize accelerated traffic on the railways of Ukraine and has all the technical capabilities to operate in high-speed traffic. The aim of the work is to study the dynamic behavior of the rolling stock under different operating conditions. popup.nrat_date 2024-12-09 Close
