Increasing the Carrying Capacity of the Solid-Body Rail Freight Car

In paper has been carried out to develop a load-bearing floor increase the carrying capacity of solid-body rail freight car. An analysis structures made it possible formulate hypothesis that car should have different cross-sectional shape. As result, was proposed, making reduce consumption materials by 1 2%. The maximum equivalent stresses (according Mises) proposed in static are 210.7 MPa, which is less than yield limit simple carbon steel. technical solution allows one 1.4-1.7 tons. solutions for future operating conditions cars make number units train 1-2 while maintaining gross weight train.
