It is concluded that the implementation of new ties and the filling has been a reason-
able solution in this case.
3.7. Crash effect analysis of the rail tank car for acid transportation
Three tank cars fell out of railway tracks in a crash. Elements of bogies and links
between the cylinder and bed, and also the cylinder tank, have suffered local plastic
deformation. The possibilities of future use of tank required some decision making and,
accordingly, defining necessary operations for eliminating crash consequences. Models of
deformed elements are presented in Fig. 20. The computational model is given in Fig. 21,
and tank deformations and stress fields for critical elements are shown in Fig. 22.
