Abstract
EN: In case of some accidents on railways there may be situations when the shock wave
appears and interacts with different objects on the railway (wagons, cargo, buildings etc.). In
these cases it is necessary to predict the possible effect of shock wave diffraction on the
different objects. Study of these problems on the basis of physical experiments (laboratory
experiment or field experiment) demand expensive and unique experimental facility. In some
cases physical experiment can’t be set. That is why mathematical simulation plays the
important role in solving problem connected with shock wave propagation. For practice it is
necessary to have predictive quick computing mathematical models which allow to perform
numerical experiment on the basis of non-powerful computers. Now, in Ukraine, there is a real
deficit of mathematical models which allow to compute quickly shock wave interaction with
different objects. The aim of this work was development of quick computing numerical model
to simulate shock wave propagation and its interaction with the wagons. The model is based on
the numerical integration of Euler equations which are written in integral form. To solve
modeling equations difference scheme of splitting was used. Results of numerical modeling are
presented.
