Abstract

The dynamic loading in the bearing structure of an open car can be decreased by means of the application of fillers in the center sill. The research included the mathematic modelling of the dynamic loading of an open car. The calculation was made for elastic, viscous, and elastic-viscous fillers. The results of calculation demonstrated that the application of viscous or elastic-viscous fillers is the most optimal technological solution in terms of decreasing the dynamic loading of an open car. The article presents the results of the computer modelling of the dynamic loading on the bearing structure of an open car. The authors determined the numerical values and the acceleration fields for the frame of an open car. The dynamic loading models were verified with an F-test. It was found that the hypothesis on adequacy was not rejected. The article also presents the results of the strength calculation for the bearing structure of an open car. The maximum equivalent stresses were concentrated in the contact area between the center sill and the body bolster beam; they amounted to 298.5 МPа, which was 9% lower than the stresses in the frame without filler. The research can be used by those who are concerned about the designing of innovative structures of freight cars and improving the operational efficiency.
