Opis:: A prototype railway wagon with a rotatable platform for an intermodal system is developed in Military University of Technology. The special railway wagon is equipped with a rotatable low flat loading floor. It can be used for transporting various types of vehicles, for example, tractors, trucks, trailers, semitrailers, cargo containers. The special wagons allows quick and convenient self-loading and unloading of vehicles and containers (no cranes needed); no platform infrastructure is required, only hardened flat surface; there is no need for hubs, terminals or special logistics; each wagon can be operated separately. A considered wagon consists of the following elements: chassis with biaxial standard Y25 bogies, frame, platform body, pneumatic systems, buffer devices, other external devices, electric equipment and hydraulic systems. A mechanism blocking rotation of a rotatable platform during transport of the load (typical semitrailers) is very important from a functionality and strength point of view of the considered wagon. Construction of such a lock allows only transmission of longitudinal load. Based on the performed FE analysis and strength tests of the wagon, it was verified that the most strenuous component of the wagon with a rotatable loading platform is a connector (lock) coupling the side of the rotatable platform with the over bogie part of the frame wagon. The selected aspects of numerical and experimental studies of the prototype railway wagon and its components are presented in the paper. FE analyses of the side lock element separated from the wagon structure are discussed as well.

Opis:: The railway wagon with a low flat rotatable loading floor was analysed in the paper. Such a structure can be used for transporting various types of vehicles such as tractors, trucks, trailers, semitrailers, cargo containers. The railway wagon allows quick and fast loading and unloading without any platform infrastructure or terminals. Only a hardened flat surface is required. Each railway wagon can be loaded-unloaded individually (no cranes needed). This construction has a wide range of application and is easy to operate. The model of a railway wagon consisted of standard carriages, undercarriages, and a rotatable loading floor was developed. The model was built of rigid solids. Between individual elements of the model, the appropriate joints and contact connections were created. The model was analysed using MSC Adams code, which allows performance of the 3D kinematic - dynamic analyses of the entire model. The analyses were carried out with use of the model of the loaded semitrailer. Passage of the railway wagon with a trailer on horizontal rails, which are the smallest standard arc with a radius 250m, was simulated at different speed. Reactions occurring in couplings of the rotatable loading floor, which are the main element of connection between the rotatable loading floor and motionless undercarriages part of the frame of the wagon, were tested. The maximum velocity at which the railway wagon can move was analysed as well. There was also examined the speed at which the wheels separate from the rails, what results in derailment of the whole wagon.

Opis:: The object of the paper is to investigate the strenght of a separated subsystem of a wagon for transport of trucks semitrailers. The wagon designed in the Department of Mechanics and Applied Computer Science, Military University of Technology, allows easy and independent loading, transport and unloading without any special equipment or additional platform infrastructure. It is possible to utilize it for transport of various vehicles types such as tractors, cars, semitrailers, containers, heavy equipment. The tests presented in the paper concern a wagon separated construction element – a side lock. It is a key subsystem of the platform allowing transfer of its loads generated in the transport position (a wagon ready to go) to the form of longitudinal forces operating in the sides of the structure. The locks are simultaneously the most strained parts of the wagon. There were carried out the numerical analyses and experimental studies of a single lock were carried out. Owing to the application of Aramis non-contact optical system of strains measurement, the lock deformations as well as the areas of the minimum and maximum main deformations were defined.
