INVESTIGATION OF LOADING STRUCTURE OF HYPER-HOPPER TWO-SECTION CARRIER DURING CARRIAGE BY RAILWAY

To increase the efficiency of operation hopper car, it is proposed to improve by dividing body into two separate sections, which facilitates possibility transporting different types cargo. In order adapt car for transportation on railway ferries in international traffic, install its pivot beams knots fastening chain ties. Determination dynamic load load-bearing structure was performed mathematical modeling. The case on-board rocking ferry taken account. solution model implemented MathCad software package. total amount acceleration acting supporting 2.4 m/s2 (0.24 g). obtained value account when calculating strength car. calculation finite element method SolidWorks Simulation results calculations established that maximum equivalent stresses are 312.3 MPa and occur node fixing. However, they do not exceed allowable values. conducted researches will promote cars, also creation developments concerning designing their perspective designs.
