Experimental determination of back wall gondola wagon with quartz sand loading in the time of wagons collision
There are the results of the experimental research of back wall gondola wagon in the time of wagons collision. To determine the pressure distribution of quartz sand throughout the height of back wall the device was designed, manufactures and fixed on the top of the wagon. To register the occurring pressure of loose goods of back wall, wagon with equipped device was run out on the wagon supporters with different speeds. The record of dynamic pressure dependencies at the control points of time was made by electrotenzonometrical method. It is characteristic, that the distribution of dynamic pressures throughout the height of back wall is not well-distributed nature and their values decrease as you get closer to the floor of the wagon.
