Determination of residual resource of flat wagons load-bearing structures with a 25-year service life
Popis výsledku v původním jazyce
The article determines the residual resource of flat wagons load-bearing structures with a 25-year service life. For this purpose, field studies of the technical condition of the load-bearing structures of flat wagons based on the wagon depot of the Foundation of the Southern Railway branch of JSC "Ukrzaliznytsia" were carried out. The flat wagon of model 13-401 was chosen as the subject. It is established that the design service life of the load-bearing structures of the studied flat wagons, taking into account the extension of their operation is not less than 18 years. The strength of the load-bearing structure of the flat wagon in the environment of SolidWorks Simulation (CosmosWorks) software by the finite element method is calculated. It is established that the maximum equivalent stresses occur in the zone of interaction of the spine beam with the pivot be equal to 337.5 MPa. Therefore, the strength of the load-bearing structure of the flat wagons is provided. The estimation of the course of the flat wagons is determined. The research was carried out in the vertical plane during the movement of the butt rail track. The calculation was performed in the MathCad software environment by the Runge-Kutta method. The assessment of the wagon is "excellent". The conducted researches will promote increase of efficiency of combined transportations in the international communication and strengthening of foreign economic positions of Ukraine in the market of transport services.
