Also, cor- rected computational schemes, mathematical models, and mathematical software for studying are developed. Based on results of analytical studies, the effects of the truck design on the wagon dynamics and wheel wear are examined, and the efficiency of remplacement of plane center plates by spherical ones, the use of elastic slide bearings in the assembly for bearing the body on trucks, and ad- ditional couplings for running gears are evaluated. Works are carried out to de- sign a transducer for measuring vibration accelerations of the body and axle boxes of railway wagons. Results present novelty for making recommendations on optional lines to improve the truck design, a schematic for bearing the body on the trucks and to introduce additional couplings in running gears;rational pa- rameters of the system for bearing the body on truck bolsters are choosen; transducers for measuring vibration acclerations up to 50g ranging from 0 to 1 kHz are developed and were under a legal metrological test. Results obtained are used in practice for improving truck gears of freight wagons.Applications - railway transport. Product Description popup.authors popup.nrat_date 2020-04-02 Close
