FIELD: transport.SUBSTANCE: roller test bench comprises frame 1 mounted at concrete bed. Simulator of track 5 is fitted at track gap 3 and comprises two rollers running in antifriction bearings. Said simulator 10 includes spring suspension, lateral, vertical and horizontal hydraulic pulsators 15, 13 and 14, respectively, turn angle and road horizontal and vertical irregularity and bogie skew transducers 18, and mounting element composed of trolley 22. Rollers 7 are driven by motor 12 mounted at track simulator to be turned by hydraulic pulsators.EFFECT: higher validity of tests and test bench efficiency, expanded operating performances.2 dwg |
