New Design of the Hatch Cover to Increase the Carrying Capacity of the Gondola Car

Abstract

The paper presents a new design of the gondola car hatch cover to increase the carrying capacity. The results of calculations the CAD model of the gondola car hatch cover showed that the maximum equivalent stresses do not exceed 216.4 MPa, the maximum equivalent displacements are 3.323 mm, and the maximum equivalent strains are 6.834×10-4. A new design of the gondola car hatch cover helps reduce the tare weight of 1.2%, i.e. increase the load capacity of the gondola car of 0.9 tons. The proposed design of the gondola hatch cover allows one to reduce the amount of rolling stock in the train by one unit while maintaining the total mass of the train.
