4. Conclusions

The worked out methods and the performed studies provide the opportunity to:

• Justify the relevance of improving the simulation methods of the loading of the body and the driver's cab during regular and emergency collisions of a moving locomotive with an obstacle on its way • Develop methods for the numerical determination of the required design parameters of energy absorption units of structural protection (passive safety system) of a locomotive (head car) • Propose and justify the criteria for estimation the effectiveness of structural protection means of newly manufactured and modernized locomotives, taking into account the design features of the rolling stock and the data on emergency collisions on the railway network of the Russian Federation • Develop methods for simulation the loading of the driver's cab during an emergency collision of a train locomotive with a mobile vehicle at a railway crossing • Develop rational finite element models of the driver's cab, allowing to estimate the effectiveness of its structural protection according to regulatory safety criteria References Krasyukov, N.F., 2014.
