SIDING SHEATHING SHAPE AND CYCLES OF VIBRATION LOADING OF GONDOLA CARS REFERENCES

The design of the side walls of freight gondola cars, designed for the use of vibration loading technology assume their sheathing with sheet profiles. Earlier held survey of technical state of gondola cars with a body height of 2365 mm, delivered for unloading and cleaning of cargo residues using vibration equipment [3] revealed an increased damageability of elements of the side walls. About 90% of gondola cars had separations of siding sheets from the side wall pillars and cracks of up to 200 mm in the corners of middle and upper corrugations of the first and second panels. This led to the fact that a new edition of GOST 22235, in force since 2010, prohibits the delivery of cars with body height of 2365 mm for unloading using vibration technology. To increase the operational reliability of such complexes, different designs, models are offered, new calculations and experiments are conducted. The article presents the results of authors’ research, conducted primarily with simulation and hybrid modeling methods, its conclusions and options of alternative sheathing profiles, tested in Yekaterinburg, showing the possibility of using overhead vibration machines for unloading gondola-cars with a height of the body of 2365 mm and with account of permissible time of operation of the rolling stock.
