DEVICE FOR CHECKING IRREGULARITIES OF RAIL TRACK Russian patent published in 1999 - IPC

FIELD: construction of railway tracks. SUBSTANCE: for each string of rail track, device has following components which are successively interconnected: unit of sensors - acceleration sensor, displacement sensor, scale amplifiers, unit for calculation of vertical trajectories of axle box, unit for calculation of vertical irregularities of rail track, and also speed sensor successively connected with speed meter. Unit for calculation of vertical trajectories of axle box has following components which are successively interconnected: double-way integrator, three-way integrator, double-way adder, and high-frequency filter. Their outputs and inputs are connected as given in description of invention. Application of aforesaid device allows for determining irregularities of rail track in wide range of lengths. EFFECT: higher efficiency. 2 dwg
