ACCELERATING CARRIAGES BRAKING TRAY Russian patent published in 2020 - IPC F42B35/00 G01M7/08 

FIELD: test equipment.

SUBSTANCE: invention relates to engineering, particularly, to equipment for high-speed track testing of articles for impact action. Tray for braking of acceleration carriages comprises cavity formed by bottom, front, rear and side walls, filled with energy-absorbing liquid medium, at that cavity along tray length is sectioned by means of transverse easily disintegrating partitions, and liquid energy-absorbing mediums filling separate sections have different rheological characteristics, with increase in consistency coefficient and corresponding change in flow index, in direction of carriage movement subject to braking.

EFFECT: reduced length of brake section of track with provision of reliable and safe braking of high-speed rail acceleration carriages, as well as increased accuracy of results of tests accompanying tests.
