Abstract

Introduction. The prospects for railway transport operation dictate the need to create new solutions to improve the efficiency of its use. The level of replenishment of the railway vehicles fleet has been insignificant in recent years, and therefore, to ensure an uninterrupted transportation process, it is advisable to adapt the existing fleet of railway vehicles to transportation of the specified range of goods. Since platform wagons are one of the most popular types of wagons in international transport, it is important to adapt their load-bearing structures to such transportation. Purpose. The paper presents the results of modelling the vertical dynamics of a platform wagon loaded by removable modules when running through a rail joint. Results. To expand the range of transported goods on a long-base platform wagon, it is proposed to use a removable module. The cargo area of the detachable module is formed by sandwich panels consisting two metal sheets with energy-absorbing material between them. However, the presence of energy-absorbing material in the sandwich panel will have an impact on the load on the load-bearing structure of the platform wagon. In this regard, the dynamics of a platform wagon loaded by removable modules in the vertical plane was studied. It is established that the maximum acceleration acting on the platform wagon in the centre of gravity is of 2.72 m/s2. This acceleration value is almost 5% lower than the acceleration acting on the platform wagon, taking into account the typical pattern of the load perception from the goods. The movement of the platform wagon when it is running in a loaded state is assessed as “excellent”. Conclusions. The conducted research will contribute to the development of recommendations for improving the efficiency of platform wagons through their situational adaptation to the transport of various types of goods.
