The paper looks at technical and economic parameters of freight wagons, and compares them to the data on average static load on Russian Railways JSC rolling stock’s wagons. It shows that it is advisable to tie introducing wagons with TPR limiting dimensions with increasing their carrying capacity and transferring to axle loads of 25 and 27 tf.

Keywords: freight wagons, carrying capacity, static load, technical and economic parameters.

The paper looks at the issues of reducing unladen weight using high-resistance steel types, and demonstrates that reducing specific amounts of metal for railway coaches when calculating under the currently active regulatory documents is impossible if welded connections are used. A set of endurance tests of standard welded connections has to be conducted.

Simulation of the operation of a shock-absorbing unit in various operating modes allows to save on design engineering. Results of tests presented in the paper indicate that laminar simulation ensures a lesser degree of divergence between calculation results and test results, compared to turbulent simulation. In order to improve simulation analysis, experimental observation of pressure indices in shock-absorbing unit’s chambers is required.

Keywords: elastomeric shock absorber, laminar simulation.

Simulation of a collision between a locomotive and a barrier produced oscillographs of parameters of dynamic interaction between simulation models of anthropometric dummies of an engine driver and an assistant, and interior elements of an electrical train’s control compartment. The influence of control compartment’s interior equipment on locomotive crew’s safety has to be considered when designing up-to-date motor train rolling stock.

On the basis of results of experimental calculation method a conclusion was reached that predicted values of wear of parts’ work surfaces would not exceed permitted limits after a wagon based on 18–9855 model bogie reaches the run of 1,000,000 km. This may lead to assigning a run of 1,000,000 km to a wagon between routine types of repair.

As a result of experimental study of fatigue strength of side frames of innovative model 18–194–1 bogie with 25 tf axle load, it was established that elastic adapter inserts used for connecting wheel sets with side frames reduce the level of their dynamic load. Elastic non-metal elements ensure not only protection against wear but also reduction of stress level in critical zones of the structure, increasing endurance characteristics and working life of load-bearing parts.

Keywords: elastic adapter insert, wheel set.
